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
CC       (ADT), an adenylated thiazole intermediate, using free sulfide as
CC       a source of sulfur. {ECO:0000256|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         ChEBI:CHEBI:57540, ChEBI:CHEBI:139151; EC=2.4.2.59;
CC         Evidence={ECO:0000256|HAMAP-Rule:MF_00304};
CC   -!- COFACTOR:
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000256|HAMAP-
CC         Rule:MF_00304};
CC   -!- PATHWAY: Cofactor biosynthesis; thiamine diphosphate biosynthesis.
CC       {ECO:0000256|HAMAP-Rule:MF_00304}.
CC   -!- SUBUNIT: Homooctamer; tetramer of dimers. {ECO:0000256|HAMAP-
CC       Rule:MF_00304}.
CC   -!- SIMILARITY: Belongs to the THI4 family. {ECO:0000256|HAMAP-
CC       Rule:MF_00304}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation
CC       of feature annotation. {ECO:0000256|HAMAP-Rule:MF_00304}.
CC   -!- CAUTION: The sequence shown here is derived from an
CC       EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is
CC       preliminary data. {ECO:0000313|EMBL:KMY66951.1}.
