Usage and Biology

Phosphite dehydrogenase is an enzyme involved in the production of phosphate for providing phosphorus source for the engineering bacteria. This part has been constructed into expression vectors to modify the metabolic pathway of phosphorus in E.coli.

KH2PO3 + H2O + NAD+ ⇒ KH2PO4 + NADH
