Protein

Light-independent protochlorophyllide reductase iron-sulfur ATP-binding protein

Gene

bchL

Organism
Rhodopseudomonas palustris (strain HaA2)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Protochlorophyllide a + reduced ferredoxin + 2 ATP + 2 H2O = chlorophyllide a + oxidized ferredoxin + 2 ADP + 2 phosphate.UniRule annotation

Cofactori

[4Fe-4S] clusterUniRule annotationNote: Binds 1 [4Fe-4S] cluster per dimer.UniRule annotation

Pathwayi: bacteriochlorophyll biosynthesis (light-independent)

This protein is involved in the pathway bacteriochlorophyll biosynthesis (light-independent), which is part of Porphyrin-containing compound metabolism.UniRule annotation
