Ferredoxin:protochlorophyllide reductase (ATP-dependent)

Ferredoxin:protochlorophyllide reductase (ATP-dependent) (EC 1.3.7.7, light-independent protochlorophyllide reductase) is an enzyme with systematic name ATP-dependent ferredoxin:protochlorophyllide-a 7,8-oxidoreductase.^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

chlorophyllide a + reduced ferredoxin + 2 ATP

\rightleftharpoons

protochlorophyllide + oxidized ferredoxin + 2 ADP + 2 phosphate

This enzyme is present in photosynthetic bacteria, cyanobacteria, green algae and gymnosperms.
