RecName: Full=Thiamine thiazole synthase;
Gene name

Comments [?]

Function Involved in the biosynthesis of the thiazole moiety of thiamine. Catalyzes the conversion of NAD and glycine to adenosine diphosphate 5-(2-hydroxyethyl)-4-methylthiazole-2-carboxylate (ADT), an adenylated thiazole intermediate, using free sulfide as a source of sulfur.
Catalytic activity RHEA:55704: glycine + hydrogen sulfide + NAD(+) = ADP-5-ethyl-4-methylthiazole-2-carboxylate + H(+) + 3 H2O + nicotinamide
Cofactor Fe(2+)
Pathway Cofactor biosynthesis; thiamine diphosphate biosynthesis.
Subunit Homooctamer; tetramer of dimers.
Similarity Belongs to the THI4 family.
