 19-122 2.20e-47

Iron-sulfur cluster assembly accessory protein; Proteins in this subfamily appear to be associated with the process of FeS-cluster assembly. The HesB proteins are associated with the nif gene cluster and the Rhizobium gene IscN has been shown to be required for nitrogen fixation. Nitrogenase includes multiple FeS clusters and many genes for their assembly. The E. coli SufA protein is associated with SufS, a NifS homolog and SufD which are involved in the FeS cluster assembly of the FhnF protein. The Azotobacter protein IscA (homologs of which are also found in E.coli) is associated which IscS, another NifS homolog and IscU, a nifU homolog as well as other factors consistent with a role in FeS cluster chemistry. A homolog from Geobacter contains a selenocysteine in place of an otherwise invariant cysteine, further suggesting a role in redox chemistry.

iron-sulfur cluster assembly protein IscA; This model represents the IscA component of the ISC system for iron-sulfur cluster assembly. The ISC system consists of IscRASU, HscAB and an Isc-specific ferredoxin. IscA previously was believed to act as a scaffold and now is seen as an iron donor protein. This clade is limited to the proteobacteria. [Biosynthesis of cofactors, prosthetic groups, and carriers, Other]
