Protein Family Models

The MOSC (MOCO sulfurase C-terminal) domain is a superfamily of beta-strand-rich domains identified in the molybdenum cofactor sulfurase and several other proteins from both prokaryotes and eukaryotes. These MOSC domains contain an absolutely conserved cysteine and occur either as stand-alone forms such as Swiss:P32157, or fused to other domains such as NifS-like catalytic domain in Molybdenum cofactor sulfurase. The MOSC domain is predicted to be a sulfur-carrier domain that receives sulfur abstracted by the pyridoxal phosphate-dependent NifS-like enzymes, on its conserved cysteine, and delivers it for the formation of diverse sulfur-metal clusters.

This small triple helical domain has been predicted to assume a topology similar to helix-turn-helix domains. These domains are found at the C-terminus of proteins related to Swiss:P32157 [1,2].
