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.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.

Catalytic activity

Cofactor

[4Fe-4S] cluster (UniProtKB | Rhea| CHEBI:49883 )

Note: Binds 1 [4Fe-4S] cluster per dimer.

Pathway

Porphyrin-containing compound metabolism; chlorophyll biosynthesis (light-independent).

Features
