Geranylgeranyl diphosphate reductase

Geranylgeranyl diphosphate reductase (, geranylgeranyl reductase, CHL P) is an enzyme with systematic name geranylgeranyl-diphosphate:NADP+ oxidoreductase. This enzyme catalises the following chemical reaction


 * phytyl diphosphate + 3 NADP+ $$\rightleftharpoons$$ geranylgeranyl diphosphate + 3 NADPH + 3 H+

This enzyme also acts on geranylgeranyl-chlorophyll a.
