CC -!- FUNCTION: Responsible for the formation of the pyrimidine heterocycle
CC in the thiamine biosynthesis pathway. Catalyzes the formation of
CC hydroxymethylpyrimidine phosphate (HMP-P) from histidine and pyridoxal
CC phosphate (PLP). The protein uses PLP and the active site histidine to
CC form HMP-P, generating an inactive enzyme. The enzyme can only undergo
CC a single turnover, which suggests it is a suicide enzyme.
CC {ECO:0000256|ARBA:ARBA00003469}.
CC -!- CATALYTIC ACTIVITY:
