Evidence for [2Fe-2S] 2+ and Linear [3Fe-4S] 1+ Clusters in a Unique Family of Glycine/Cysteine-Rich Fe-S Proteins from Megavirinae Giant Viruses

Archive ouverte | Villalta, Alejandro | CCSD

International audience. We have discovered a protein with an amino acid composition exceptionally rich in glycine and cysteine residues in the giant virus mimivirus. This small 6 kDa protein is among the most abunda...

Iron insertion at the assembly site of the ISCU scaffold protein is a conserved process initiating Fe–S cluster biosynthesis

Archive ouverte | Srour, Batoul | CCSD

International audience. Iron−sulfur (Fe−S) clusters are prosthetic groups of proteins biosynthesized on scaffold proteins by highly conserved multi-protein machineries. Biosynthesis of Fe−S clusters into the ISCU sc...

The bacterial MrpORP is a novel Mrp/NBP35 protein involved in iron-sulfur biogenesis

Archive ouverte | Pardoux, Romain | CCSD

International audience. Despite recent advances in understanding the biogenesis of iron-sulfur (Fe-S) proteins, most studies focused on aerobic bacteria as model organisms. Accordingly, multiple players have been pr...
