A critical role is played by residue His 159 in the catalytic mechanism of DHDPR. Replacement of this residue with an alanine or a glutamine is reported to result in a 150-200fold reduction in catalytic rate as well as a 6fold increase in KM. His 159 has been proposed to act as a general acid during catalysis, providing the proton required after hydride addition. No activity with beta-hydroxypyruvate and 3-fluoropyruvate
