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.

This family consists of several bacterial thiazole biosynthesis protein G sequences. ThiG , together with ThiF and ThiH, is proposed to be involved in the synthesis of 4-methyl-5-(b-hydroxyethyl)thiazole (THZ) which is an intermediate in the thiazole production pathway [1]. This family also includes triosephosphate isomerase and pyridoxal 5'-phosphate synthase subunit PdxS.	Domain
