Function and Biology Details

Reaction catalysed:
(1) 4-amino-2-methyl-5-diphosphomethylpyrimidine + 2-((2R,5Z)-2-carboxy- 4-methylthiazol-5(2H)-ylidene)ethyl phosphate = diphosphate + thiamine phosphate + CO(2). (2) 4-amino-2-methyl-5-diphosphomethylpyrimidine + 2-(2-carboxy-4- methylthiazol-5-yl)ethyl phosphate = diphosphate + thiamine phosphate + CO(2). (3) 4-amino-2-methyl-5-diphosphomethylpyrimidine + 4-methyl-5- (2-phosphono-oxyethyl)thiazole = diphosphate + thiamine phosphate.
