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

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.
