ABSTRACT
Iron-sulfur (Fe-S) clusters are among the oldest protein cofactors, and Fe-S cluster-based chemistry has shaped the cellular metabolism of all living organisms. Over the last 30 years, thanks to molecular biology and genetic approaches, numerous actors for Fe-S cluster assembly and delivery to apotargets have been uncovered. In prokaryotes, Escherichia coli is the best-studied for its convenience of growth and its genetic amenability. During evolution, redundant ways to secure the supply of Fe-S clusters to the client proteins have emerged in E. coli. Disrupting gene expression is essential for gene function exploration, but redundancy can blur the interpretations as it can mask the role of important biogenesis components. This chapter describes molecular biology and genetic strategies that have permitted to reveal the E. coli Fe-S cluster conveying component network, composition, organization, and plasticity. In this chapter, we will describe the following genetic methods to investigate the importance of E. coli Fe-S cluster carriers one-step inactivation of chromosomal genes in E. coli using polymerase chain reaction (PCR) products, P1 transduction, arabinose-inducible expression system, mevalonate (MVA) genetic by-pass, sensitivity tests to oxidative stress and iron starvation, ß-galactosidase assay, gentamicin survival test, and Hot Fusion cloning method.
