Geranylgeranyl diphosphate reductase (EC 1.3.1.83, geranylgeranyl reductase, CHL P) is an enzyme with systematic name geranylgeranyl-diphosphate:NADP+ oxidoreductase. [1] [2] This enzyme catalyses the following chemical reaction
The substrate of this enzyme is geranylgeranyl pyrophosphate, which reacts with three equivalents of reduced nicotinamide adenine dinucleotide phosphate (NADPH), and three protons. The product is phytyl diphosphate and oxidised NADP+. [3] It can also act on geranylgeranyl-chlorophyll a. [4]
