Phosphoglycerate dehydrogenase

The enzyme Phosphoglycerate dehydrogenase (PDH) catalyzes the reaction to convert 3-phospho-D-glycerate (P3G) to phosphonooxypyruvate (PHP). The cofactors NADH and NAD^{+ are not considered in this reaction.}

Chemical equation

$P3G \rightleftharpoons PHP$

Rate equation

Modified rate equation is used

$\frac{ serA*K_{cat}A.\frac{[3PG]}{Ka_{3PG}}}{\frac{1 + \frac{[3PG]}{Ka_{3PG}} + \frac{[PHP]}{Ka_{PHP}} }{1+ \frac{[SER]}{KiA_{SER}}}}$
