The Crystal Structure of Candida glabrata THI6, a Bifunctional Enzyme involved in Thiamin Biosyhthesis of Eukaryotes


Function and Biology Details

Reactions catalysed:
4-amino-2-methyl-5-diphosphomethylpyrimidine + 2-((2R,5Z)-2-carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate = diphosphate + thiamine phosphate + CO(2)
ATP + 4-methyl-5-(2-hydroxyethyl)thiazole = ADP + 4-methyl-5-(2-phosphonooxyethyl)thiazole
