Template:STRUCTURE 3agb

F218V mutant of the substrate-free form of red chlorophyll catabolite reductase from Arabidopsis thaliana

Template:ABSTRACT PUBMED 20727901

Function

[RCCR_ARATH] Catalyzes the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of pheophorbide a (pheide a) to a primary fluorescent catabolite (pFCC). Works in a two-step reaction with pheophorbide a oxygenase (PaO) by reducing the C20/C1 double bond of the intermediate, RCC.[1]

About this Structure
