Organism

Synechocystis sp. (strain PCC 6803 / Kazusa) [Reference proteome] [HAMAP]

Taxonomic identifier

1111708 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Cyanobacteria › Oscillatoriophycideae › Chroococcales › Synechocystis › Synechocystis sp. PCC 6803

Protein attributes

Sequence length	469 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent By similarity. HAMAP-Rule MF_00352
Pathway	Porphyrin biosynthesis; chlorophyll biosynthesis (light-independent). HAMAP-Rule MF_00352
Subunit structure	Protochlorophyllide reductase is thought to be composed of three subunits; ChlL, ChlN and ChlB. Could form a heterotetramer of two ChlB and two ChlN subunits By similarity.
Sequence similarities	Belongs to the BchN/ChlN family.
