Application
D-Lactic Dehydrogenase can be used to generate inhibitors of angiotensin converting enzyme by catalyzing the production of the intermediate (R)-2-Hydroxy-4-phenylbutyric acid.
D-Lactic dehydrogenase has been used in a study to assess mechanisms of active transport in isolated membrane vesicles. It has also been used in a study to investigate β-galactoside transport in bacterial membrane preparations.
Unit Definition
One unit will reduce 1.0 μmole of pyruvate to D-lactate per min at pH 7.0 at 25 °C.

The transport of beta-galactosides by isolated membrane preparations from Escherichia coli strains containing a functional y gene is markedly stimulated by the conversion of D-lactate to pyruvate. The addition of D-lactate to these membrane preparations produces a 19-fold increase in

(R)-2-Hydroxy-4-phenylbutyric acid, an intermediate in the manufacture of inhibitors of angiotensin converting enzyme, can be produced continuously in an enzyme membrane reactor by enzymatic reduction of its corresponding alpha-keto acid. D-Lactate dehydrogenase (D-LDH) from Staphylococcus epidermidis was chosen as the
