Paleoproteomics explained to youngsters: how did the wedding of two-dimensional electrophoresis and protein sequencing spark proteomics on: let there be light.

Taking the opportunity of the 20th anniversary of the word "proteomics", this young adult age is a good time to remember how proteomics came from enormous progress in protein separation and protein microanalysis techniques, and from the conjugation of these advances into a high performance and streamlined working setup. However, in the history of the almost three decades that encompass the first attempts to perform large scale analysis of proteins to the current high throughput proteomics that we can enjoy now, it is also interesting to underline and to recall how difficult the first decade was. Indeed when the word was cast, the battle was already won. This recollection is mostly devoted to the almost forgotten period where proteomics was being conceived and put to birth, as this collective scientific work will never appear when searched through the keyword "proteomics". BIOLOGICAL SIGNIFICANCE: The significance of this manuscript is to recall and review the two decades that separated the first attempts of performing large scale analysis of proteins from the solid technical corpus that existed when the word "proteomics" was coined twenty years ago. This recollection is made within the scientific historical context of this decade, which also saw the blossoming of DNA cloning and sequencing.

Laying the groundwork for proteomics: mass spectrometry from 1958 to 1988.

The development of mass spectrometric methods in peptide and protein chemistry in the author's laboratory is reviewed, from the first determination of the amino acid sequence of small peptides in the late 1950s to its use for the determination of the primary structure of large proteins by a combination of mass spectrometry and DNA sequencing in the late 1980s.

Collecting, comparing, and computing sequences: the making of Margaret O. Dayhoff's Atlas of Protein Sequence and Structure, 1954-1965.

Collecting, comparing, and computing molecular sequences are among the most prevalent practices in contemporary biological research. They represent a specific way of producing knowledge. This paper explores the historical development of these practices, focusing on the work of Margaret O. Dayhoff, Richard V. Eck, and Robert S. Ledley, who produced the first computer-based collection of protein sequences, published in book format in 1965 as the Atlas of Protein Sequence and Structure. While these practices are generally associated with the rise of molecular evolution in the 1960s, this paper shows that they grew out of research agendas from the previous decade, including the biochemical investigation of the relations between the structures and function of proteins and the theoretical attempt to decipher the genetic code. It also shows how computers became essential for the handling and analysis of sequence data. Finally, this paper reflects on the relationships between experimenting and collecting as two distinct "ways of knowing" that were essential for the transformation of the life sciences in the twentieth century.

A new insight into Sanger's development of sequencing: from proteins to DNA, 1943-1977.

Fred Sanger, the inventor of the first protein, RNA and DNA sequencing methods, has traditionally been seen as a technical scientist, engaged in laboratory bench work and not interested at all in intellectual debates in biology. In his autobiography and commentaries by fellow researchers, he is portrayed as having a trajectory exclusively dependent on technological progress. The scarce historical scholarship on Sanger partially challenges these accounts by highlighting the importance of professional contacts, institutional and disciplinary moves in his career, spanning from 1940 to 1983. This paper will complement such literature by focusing, for the first time, on the transition of Sanger's sequencing strategies from degrading to copying the target molecule, which occurred in the late 1960s as he was shifting from protein and RNA to DNA sequencing, shortly after his move from the Department of Biochemistry to the Laboratory of Molecular Biology, both based in Cambridge (U.K.). Through a reinterpretation of Sanger's papers and retrospective accounts and a pioneering investigation of his laboratory notebooks, I will claim that sequencing shifted from the working procedures of organic chemistry to those of the emergent molecular biology. I will also argue that sequencing deserves a history in its own right as a practice and not as a technique subordinated to the development of molecular biology or genomics. My proposed history of sequencing leads to a reappraisal of current STS debates on bioinformatics, biotechnology and biomedicine.

The protein data bank. Bridging the gap between the sequence and 3D structure world.

The protein data bank (PDB), at Brookhaven National Laboratory, is a database containing information on experimentally determined three-dimensional structures of proteins, nucleic acids, and other biological macromolecules, with approximately 9000 entries. The PDB has a 27-year history of service to a global community of researchers, educators, and students in a wide variety of scientific disciplines. Data are easily submitted via PDB's WWW-based tool AutoDep, in either PDB or mmCIF format, and are most conveniently examined via PDB's WWW-based tool 3DB Browser. Collaborative centers have been, and continue to be, established worldwide to assist in data deposition, archiving, and distribution.
