This entry represents an archaeal MoaD-like domain with a ubiquitin-like fold found in various archaebacterial proteins. These proteins have a highly conserved Gly-Gly motif at their C-terminus, a hallmark of the MoaD/ThiS/ubiquitin superfamily [1,2]. The bacterial MoaD protein functions as a sulfur carrier in molybdenum cofactor (Moco) biosynthesis, with the C-terminal Gly-Gly motif being essential for activation by the MoeB enzyme. After activation, MoaD receives a sulfur atom to form a thiocarboxylate intermediate that acts as a sulfur donor. Based on the conserved Gly-Gly motif and association with ThiS genes and MoaB-like proteins, these archaeal proteins likely function as sulfur carriers in cofactor biosynthesis pathways, similar to their bacterial counterparts.

ThiS (thiaminS) is a 66 aa protein involved in sulphur transfer Swiss:O32583. ThiS is coded in the thiCEFSGH operon in E. coli. This family of proteins have two conserved Glycines at the COOH terminus. Thiocarboxylate is formed at the last G in the activation process. Sulphur is transferred from ThiI to ThiS in a reaction catalysed by IscS [1]. MoaD, Swiss:P30748 a protein involved sulphur transfer in molybdopterin synthesis, is about the same length and shows limited sequence similarity to ThiS. Both have the conserved GG at the COOH end.
