Protein attributes

Sequence length	256 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the rearrangement of 1-deoxy-D-xylulose 5-phosphate (DXP) to produce the thiazole phosphate moiety of thiamine. Sulfur is provided by the thiocarboxylate moiety of the carrier protein ThiS. In vitro, sulfur can be provided by H2S By similarity. HAMAP-Rule MF_00443
Catalytic activity	1-deoxy-D-xylulose 5-phosphate + 2-iminoacetate + thiocarboxy-adenylate-[sulfur-carrier protein ThiS] = 2-((2R,5Z)-2-carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate + [sulfur-carrier protein ThiS] + 2 H2O. HAMAP-Rule MF_00443
Pathway	Cofactor biosynthesis; thiamine diphosphate biosynthesis. HAMAP-Rule MF_00443
Subunit structure	Homotetramer. Forms heterodimers with either ThiH or ThiS By similarity.
Subcellular location	Cytoplasm By similarity HAMAP-Rule MF_00443.
Sequence similarities	Belongs to the ThiG family.
