Journal ArticleDOI
Extracellular enzymes and pathogenesis of soft-rot erwinia
TL;DR: Diversity notwithstanding, these bacteria are related genetically to other en terobacteria such as Escherichia coli and Salmonella typhimurium that have served well as model systems for genetic and physiological studies.
Journal ArticleDOI
Oxidative stress, protein damage and repair in bacteria
TL;DR: This Review discusses the current understanding of the reducing systems that enable bacteria to repair oxidatively damaged cysteine and methionine residues in the cytoplasm and in the bacterial cell envelope, and highlights the importance of these repair systems in bacterial physiology and virulence.
Journal ArticleDOI
Repair of oxidized proteins : Identification of a new methionine sulfoxide reductase
Régis Grimaud,Benjamin Ezraty,Jennifer K. Mitchell,Daniel Lafitte,Claudette Briand,Peter J. Derrick,Frédéric Barras +6 more
TL;DR: A new methionine sulfoxide reductase is identified, which is referred to as MsrB, the gene of which is present in genomes of eubacteria, archaebacteria, and eucaryotes and is required for cadmium resistance of E. coli.
Journal ArticleDOI
Building Fe–S proteins: bacterial strategies
Béatrice Py,Frédéric Barras +1 more
TL;DR: The multiprotein systems that are required to build Fe-S proteins have been identified, but the in vivo roles of some of the components remain to be clarified and the way in which cellular Fe–S cluster trafficking pathways are organized remains a key issue for future studies.
Journal ArticleDOI
Iron/sulfur proteins biogenesis in prokaryotes: formation, regulation and diversity.
TL;DR: Basic principles and recent advances in the understanding of the prokaryotic Fe/S biogenesis ISC and SUF systems are reviewed and an effort was made to provide, based on the E. coli system, a general classification associating a given domain with a given function to help next search and annotation of genomes.
