CC -!- FUNCTION: Essential for thiamine biosynthesis. Bifunctional enzyme that
CC catalyzes the phosphorylation of hydroxymethylpyrimidine phosphate
CC (HMP-P) to HMP-PP and condenses 4-methyl-5-(beta-hydroxyethyl)thiazole
CC monophosphate (THZ-P) and 2-methyl-4-amino-5-hydroxymethyl pyrimidine
CC pyrophosphate (HMP-PP) to form thiamine monophosphate (TMP).
