Structural highlights
FunctionTHI5_CANAW Responsible for the formation of the pyrimidine heterocycle in the thiamine biosynthesis pathway. Catalyzes the formation of hydroxymethylpyrimidine phosphate (HMP-P) from histidine and pyridoxal phosphate (PLP). The protein uses PLP and the active site histidine to form HMP-P, generating an inactive enzyme. The enzyme can only undergo a single turnover, which suggests it is a suicide enzyme.[1] References
