FEATURES

DESCRIPTION

Also known as RCCR_ARATH, RCCR, ACD2. 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. Belongs to the chlorophyll catabolic enzymes (CCEs). Homodimer (PubMed:19374909, PubMed:20727901). Interacts with HCAR (PubMed:23200839). Interacts with SGR1, NYC1, NOL, PPH, PAO and the LHCII complex (PubMed:22366162). Part of a SGR1-CCE-LHCII complex, which acts in chlorophyll breakdown (PubMed:22366162).
