Protein Family Models

This family is involved in iron-sulphur cluster biosynthesis [3]. Its members include proteins that are involved in nitrogen fixation such as the HesB and HesB-like proteins [1] [2]. [1]. 10217509.

This is an alignment of the carboxy-terminal domain. This is the only common region between the NifU protein from nitrogen-fixing bacteria and rhodobacterial species. The biochemical function of NifU is unknown [1]. [1]. 8048161. The modular structure of NifU proteins.. Ouzounis C, Bork P, Sander C;. Trends Biochem Sci 1994;19:199-200. (from Pfam)

IscR (TIGR02010) is an iron-sulfur cluster-binding transcriptional regulator (see Genome Property GenProp0138). Members of this protein family include YhgI, whose expression is under control of IscR, and show sequence similarity to IscA, a known protein of iron-sulfur cluster biosynthesis. These two lines of evidence strongly suggest a role as an iron-sulfur cluster biosynthesis protein. An older study designated this protein GntY and suggested a role for it and for the product of an adjacent gene, based on complementation studies, in gluconate utilization.
