A Conversation with James Ntambi.

An interview with James M. Ntambi, professor of biochemistry and the Katherine Berns Van Donk Steenbock Professor in Nutrition, College of Agricultural and Life Sciences, at the University of Wisconsin-Madison, took place via Zoom in April 2022. He was interviewed by Patrick J. Stover, director of the Institute for Advancing Health through Agriculture and professor of nutrition and biochemistry and biophysics at Texas A&M University. Dr. James Ntambi is a true pioneer in the field of nutritional biochemistry. He was among the very first to discover and elucidate the role that diet and nutrients play in regulating metabolism through changes in the expression of metabolic genes, focusing on the de novo lipogenesis pathways. As an African immigrant from Uganda, his love of science and his life experiences in African communities suffering from severe malnutrition molded his scientific interests at the interface of biochemistry and nutrition. Throughout his career, he has been an academic role model, a groundbreaking nutrition scientist, and an educator. His commitment to experiential learning through the many study-abroad classes he has hosted in Uganda has provided invaluable context for American students in nutrition. Dr. Ntambi's passion for education and scientific discovery is his legacy, and the field of nutrition has benefited enormously from his unique perspectives and contributions to science that are defined by his scientific curiosity, his generosity to his students and colleagues, and his life experiences. The following is an edited transcript.

My lifelong dedication to bile acid research.

It is a great honor to be invited to write a reflections article on my scientific journey and lifelong bile acid research for the Journal of Biological Chemistry, in which I am proud to have published 24 articles. I have also published 21 articles in the Journal of Lipid Research, another journal of the American Society of Biochemistry and Molecular Biology. I begin my reflections from my early education in Taiwan, my coming to America for graduate study, and continue with my postdoctoral training in cytochrome P450 research, and my lifelong bile acid research career at Northeast Ohio Medical University. I have witnessed and helped in the transformation of this rural not so visible medical school to a well-funded leader in liver research. Writing this reflections article on my long and rewarding journey in bile acid research brings back many good memories. I am proud of my scientific contributions and attribute my academic success to hard work, perseverance, good mentoring, and networking. I hope these reflections of my academic career would help inspire young investigators to pursue an academic career in biochemistry and metabolic diseases.

Reflections on the 50-year history of the Federation of Asian and Oceanian Biochemists and Molecular Biologists (FAOBMB).

The Federation of Asian and Oceanian Biochemists and Molecular Biologists, Inc. (FAOBMB) celebrates its Golden Jubilee in 2022. Established in August 1972 as a regional grouping of three national societies of biochemists in Australia, India and Japan, it took the name Federation of Asian and Oceanian Biochemists (FAOB). The Federation rapidly grew to encompass another 12 national societies (or groups) of biochemists within 6 years, eventually increasing the number of Constituent Members to 21 by 2014. FAOB soon established regular scientific meetings, including triennial Congresses and annual Symposia; from 1980 FAOB Travel Fellowships enabled regional young scientists to participate in them. In 1992, FAOB was constituted as an Incorporated Association in Victoria, Australia, changing its name 1 year later (yielding the acronym FAOBMB). A printed Newsletter/Bulletin was distributed through each Constituent Society or Group from 1972 to 1999. With the advent of the internet and email in the late 1990s, communication rapidly improved, such that the first webpage of FAOBMB was set up in 1995. From the inception of the Federation, an international journal sponsored by FAOB was foreshadowed but only commenced in 1997, sadly lasting only 6 years. Education in biochemistry and molecular biology became prominent in FAOBMB from the 1990s. In the 21st century, awards to high-achieving scientists and educationists were introduced, the first being the Young Scientist Awards in 2006. The Fellowships program was extended to young educationists in 2018. FAOB(MB) has been supported by the International Union of Biochemistry (and Molecular Biology) almost its entire history, mostly for support of Congresses, Conferences and Symposia, but also for Young Scientist Programs. The most recent challenge to FAOBMB came with the COVID-19 pandemic. Executive Committee and the Constituent Members rapidly adapted to virtual communications for their administrative meetings and Education Symposia, and a memorable Congress was held totally on-line in 2021.

Assay of the enzymes of glutathione biosynthesis.

This article is dedicated to the late long-time Editor-in-Chief of Analytical Biochemistry, William Jakoby. As a graduate student, I remember reading many articles in Analytical Biochemistry and Methods in Enzymology, both volumes that Bill edited. I first met him as a graduate student presenting at the American Society of Biochemistry (and Molecular Biology) meetings. My Ph.D. advisor, Alton Meister, would bring over well-known biochemists and introduce me as Dr. Anderson, leaving me a bit tongue-tied being that I was still actually a humble graduate student! I next met Bill at my first Analytical Biochemistry Executive Editors meeting in San Diego when he was Editor-in-Chief Emeritus; I felt honored to be on the same board with him and serving the journal to which he had brought to prominence. His eyes were piercing and he was so sharp; his knowledge was both broad and deep. Since much of the large body of Bill's research was on glutathione S-transferases, my article focuses on the assay of the enzymes that synthesize glutathione, a substrate for glutathione S-transferases.

Molecularización, genetización y centros de referencia: el Instituto de Bioquímica Clínica de Barcelona (1969-1980) / Molecularization, geneticization and reference centers: the Institute of Clinical Biochemistry of Barcelona (1969-1980)

En conjunto, la molecularización y la genetización de la biomedicina del siglo XX construyeron un enorme listado de enfermedades, la mayoría raras, con unas necesidades asistenciales muy específicas, una gran dependencia del laboratorio e importantes dificulta-des para la creación de expertos. Estos fenómenos indujeron grandes cambios en las redes asistenciales y en los itinerarios diagnósticos. Uno de los más significativos fue la aparición de centros de referencia en los que concentrar los recursos humanos y materiales para enferme-dades tan poco prevalentes. A partir del estudio del Instituto de Bioquímica Clínica “Fundación Juan March” de Barcelona, este artículo aborda la aparición de estos nuevos espacios en la España del Tardofranquismo. Farmacéuticos, pediatras, políticos y gestores sanitarios, con sus diferentes intereses, aparecen como actores involucrados en la forja de un instituto que en pocos años se erigió como centro de referencia nacional para enfermedades de depósito lisosomal. El trabajo revela la importancia que tuvo la sensibilidad social sobre la discapacidad intelectual como motor (y excusa) de la iniciativa, el papel de las fundaciones filantrópicas y la influencia de la ciencia norteamericana en todo el proceso, en circulación a través de los viajes de los científicos españoles al extranjero (AU)

Welcome to Biochemistry Volume 1: No Hyphen Required.

The founding of the journal Biochemistry by the American Chemical Society 60 years ago was a highlight of the Society's growing commitment to chemically driven biochemistry. It was a commitment that was nearly an additional 60 years in the making. In that time, biological chemistry was becoming more molecularly focused. Its relationship to the traditional chemical disciplines became apparent to a generation of young chemists, who grappled with defining the field's core chemical principles and creating new areas of research for a new journal. The path to Biochemistry was exciting, but it was also complex and difficult. Even its naming was arguable.

The Birth of Genomic Enzymology: Discovery of the Mechanistically Diverse Enolase Superfamily.

Enzymes are categorized into superfamilies by sequence, structural, and mechanistic similarities. The evolutionary implications can be profound. Until the mid-1990s, the approach was fragmented largely due to limited sequence and structural data. However, in 1996, Babbitt et al. published a paper in Biochemistry that demonstrated the potential power of mechanistically diverse superfamilies to identify common ancestry, predict function, and, in some cases, predict specificity. This Perspective describes the findings of the original work and reviews the current understanding of structure and mechanism in the founding family members. The outcomes of the genomic enzymology approach have reached far beyond the functional assignment of members of the enolase superfamily, inspiring the study of superfamilies and the adoption of sequence similarity networks and genome context and yielding fundamental insights into enzyme evolution.

Alexander Spirin on Molecular Machines and Origin of Life.

Once it was believed that ribosomal RNA encodes proteins, and GTP hydrolysis supplies the energy for protein synthesis. Everything has changed, when Alexander Spirin joined the science. It turned out that proteins are encoded by a completely different RNA, and GTP hydrolysis only accelerates the process already provided with energy. It was Spirin who first put forward the idea of a Brownian ratchet and explained how and why molecular machines could arise in the RNA world.

What's in a name? From "fluctuation fit" to "conformational selection": rediscovery of a concept.

Rediscoveries are not rare in biology. A recent example is the re-birth of the "fluctuation fit" concept developed by F. B. Straub and G. Szabolcsi in the sixties of the last century, under various names, the most popular of which is the "conformational selection". This theory offers an alternative to the "induced fit" concept by Koshland for the interpretation of the mechanism of protein-ligand interactions. A central question is whether the ligand induces a conformational change (as described by the induced fit model) or rather selects and stabilizes a complementary conformation from a pre-existing equilibrium of various states of the protein (according to the fluctuation fit/conformational selection model). Straub and Szabolcsi's role and the factors hindering the spread of the fluctuation fit theory are discussed in the context of the history of the Hungarian biology in the 1950s and 1960s.

Genetic Code Expansion: A Brief History and Perspective.

Since the establishment of site-specific mutagenesis of single amino acids to interrogate protein function in the 1970s, biochemists have sought to tailor protein structure in the native cell environment. Fine-tuning the chemical properties of proteins is an indispensable way to address fundamental mechanistic questions. Unnatural amino acids (UAAs) offer the possibility to expand beyond the 20 naturally occurring amino acids in most species and install new and useful chemical functions. Here, we review the literature about advances in UAA incorporation technology from chemoenzymatic aminoacylation of modified tRNAs to in vitro translation systems to genetic encoding of UAAs in the native cell environment and whole organisms. We discuss innovative applications of the UAA technology to challenges in bioengineering and medicine.
