ErpA, an iron sulfur (Fe S) protein of the A-type essential for respiratory metabolism in Escherichia coli

Archive ouverte | Loiseau, Laurent | CCSD

International audience

The CsdA cysteine desulphurase promotes Fe/S biogenesis by recruiting Suf components and participates to a new sulphur transfer pathway by recruiting CsdL (ex-YgdL), a ubiquitin-modifying-like protein

Archive ouverte | Trotter, Valentine | CCSD

International audience. Cysteine desulphurases are primary sources of sulphur that can eventually be used for Fe/S biogenesis or thiolation of various cofactors and tRNA. Escherichia coli contains three such enzymes...

Quinolinate synthase, an iron-sulfur enzyme in NAD biosynthesis

Archive ouverte | Ollagnier de Choudens, Sandrine | CCSD

International audience. Nicotinamide adenine dinucleotide (NAD) plays a crucial role as a cofactor in numerous essential redox biological reactions. NAD derives from quinolinic acid which is synthesized in E. coli f...
