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:0000250|UniProtKB:P43534}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 Fe(3+) + 4 H2O + L-histidyl-[4-amino-5-hydroxymethyl-2-
CC methylpyrimidine phosphate synthase] + N(6)-(pyridoxal phosphate)-L-
CC lysyl-[4-amino-5-hydroxymethyl-2-methylpyrimidine phosphate synthase]
CC = (2S)-2-amino-5-hydroxy-4-oxopentanoyl-[4-amino-5-hydroxymethyl-2-
CC methylpyrimidine phosphate synthase] + 3-oxopropanoate + 4-amino-2-
CC methyl-5-(phosphooxymethyl)pyrimidine + 2 Fe(2+) + 2 H(+) + L-lysyl-
CC [4-amino-5-hydroxymethyl-2-methylpyrimidine phosphate synthase];
