Protein
Light-independent protochlorophyllide reductase subunit N
Organism
Chaetosphaeridium globosum
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 NB-protein (ChlN-ChlB) is the catalytic component of the complex.
Similarity
Belongs to the BchN/ChlN family.
