Gene

chlL

Organism
Cyanothece sp. (strain PCC 8801) (Synechococcus sp. (strain PCC 8801 / RF-1))
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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: chlorophyll biosynthesis (light-independent)

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

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
