Function
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.
Catalytic activity
- [sulfur-carrier protein ThiS]-C-terminal Gly-NH-CH2-C(O)SH + 2-iminoacetate + 1-deoxy-D-xylulose 5-phosphate = [sulfur-carrier protein ThiS]-C-terminal Gly-Gly + 2-[(2R,5Z)-2-carboxy-4-methylthiazol-5(2H)-ylidene]ethyl phosphate + 2 H2O + 2 H+
Pathway
Cofactor biosynthesis; thiamine diphosphate biosynthesis.
