FeS cluster assembly protein sufB (P77522)

Identification
Name:FeS cluster assembly protein sufB
Synonyms:Not Available
Gene Name:sufB
Enzyme Class:Not Available
Biological Properties
General Function:Involved in iron-sulfur cluster assembly
Specific Function:The sufBCD complex acts synergistically with sufE to stimulate the cysteine desulfurase activity of sufS. The sufBCD complex contributes to the assembly or repair of oxygen-labile iron-sulfur clusters under oxidative stress. May facilitate iron uptake from extracellular iron chelators under iron limitation
