Entry
Name
geranylgeranyl-bacteriochlorophyllide a reductase;
geranylgeranyl-bacteriopheophytin reductase;
bchP (gene name)
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With NAD+ or NADP+ as acceptor
BRITE hierarchy
Sysname
bacteriochlorophyll-a:NADP+ oxidoreductase (geranylgeranyl-reducing)
Reaction(IUBMB)
bacteriochlorophyll a + 3 NADP+ = geranylgeranyl bacteriochlorophyllide a + 3 NADPH + 3 H+ [RN:
R11226 ]
Reaction(KEGG)
Substrate
Product
Comment
The enzyme catalyses the successive reduction of the geranylgeraniol esterifying group to phytol, reducing three out of four double bonds, and transforming geranylgeranyl bacteriochlorophyllide a via dihydrogeranylgeranyl bacteriochlorophyllide a and tetrahydrogeranylgeranyl bacteriochlorophyllide a to bacteriochlorophyll a. The enzyme can also accept the pheophytin derivative geranylgeranyl bacteriopheophytin, converting it to bacteriopheophytin a.
