Function
function
Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The L component serves as a unique electron donor to the NB-component of the complex, and binds Mg-ATP.
Catalytic activity
- chlorophyllide a + oxidized 2[4Fe-4S]-[ferredoxin] + 2 ADP + 2 phosphate = protochlorophyllide a + reduced 2[4Fe-4S]-[ferredoxin] + 2 ATP + 2 H2O
