RC STRAIN=ATCC 700980 / DSM 13731 / RS-1; RX PubMed=19675025; DOI=10.1101/gr.088906.108; RA Nakazawa H., Arakaki A., Narita-Yamada S., Yashiro I., Jinno K., RA Aoki N., Tsuruyama A., Okamura Y., Tanikawa S., Fujita N., RA Takeyama H., Matsunaga T.; RT "Whole genome sequence of Desulfovibrio magneticus strain RS-1 RT revealed common gene clusters in magnetotactic bacteria."; RL Genome Res. 19:1801-1808(2009). 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: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}.
