CC -!- FUNCTION: Involved in the biosynthesis of the thiazole moiety of
CC thiamine. Catalyzes the conversion of NAD and glycine to adenosine
CC diphosphate 5-(2-hydroxyethyl)-4-methylthiazole-2-carboxylate (ADT), an
CC adenylated thiazole intermediate, using free sulfide as a source of
CC sulfur. {ECO:0000255|HAMAP-Rule:MF_00304}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glycine + hydrogen sulfide + NAD(+) = ADP-5-ethyl-4-
CC methylthiazole-2-carboxylate + H(+) + 3 H2O + nicotinamide;
CC Xref=Rhea:RHEA:55704, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17154, ChEBI:CHEBI:29919, ChEBI:CHEBI:57305,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:139151; EC=2.4.2.59;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00304};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00304};
CC -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00304}.
CC -!- SUBUNIT: Homooctamer; tetramer of dimers. {ECO:0000255|HAMAP-
CC Rule:MF_00304}.
CC -!- SIMILARITY: Belongs to the THI4 family. {ECO:0000255|HAMAP-
CC Rule:MF_00304}.
