Probable chlorophyll(ide) b reductase NYC1, chloroplastic; Encodes a chlorophyll b reductase involved in the degradation of chlorophyll b and LHCII (light harvesting complex II) (496 aa)
0.983
HCAR
Coenzyme F420 hydrogenase family / dehydrogenase, beta subunit family; Probable iron-sulfur flavoprotein that converts 7- hydroxymethyl chlorophyll a to chlorophyll a using ferredoxin as a reducing equivalent. Catalyzes the reduction of a hydroxymethyl group to a methyl group. Belongs to the chlorophyll catabolic enzymes (CCEs) (462 aa)
0.983
PPH
Pheophytinase, chloroplastic; Alpha/beta hydrolase dephytylating specifically the Mg- free chlorophyll pigment (pheophytin), yielding pheophorbide. No activity on chlorophyll. Belongs to the chlorophyll catabolic enzymes (CCEs) (484 aa)
0.980
CLH1
Chlorophyllase-1; Chlorophyllase is the first enzyme involved in chlorophyll degradation. It catalyzes the hydrolysis of the ester bond to yield chlorophyllide and phytol. AtCLH1 lacks a typical signal sequence for the chloroplast. Its expression is induced rapidly by methyljasmonate, a known promoter of senescence and chlorophyll degradation; Belongs to the AB hydrolase superfamily. Lipase family (324 aa)
0.979
NOL
Chlorophyll(ide) b reductase NOL, chloroplastic; Required for chlorophyll b degradation. Chlorophyll b, chlorophyllide b, pheophorbide b and pheophytin b can be used as substrates. Belongs to the chlorophyll catabolic enzymes (CCEs) (348 aa)
0.975
CLH2
Chlorophyllase-2, chloroplastic; Encodes a chlorophyllase, the first enzyme in chlorophyll degradation. It catalyzes the hydrolysis of the ester bond to chlorophyllide and phytol. AtCLH2 has a typical signal sequence for the chloroplast. Gene expression does not respond to methyljasmonate, a known promoter of senescence and chlorophyll degradation (318 aa)

ACD1
Pheophorbide a oxygenase family protein with Rieske [2Fe-2S] domain; 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 red chlorophyll catabolite reductase (RCCR). Creates the intermediate RCC through the opening of the porphyrin macrocycle by the introduction of one atom of molecular oxygen at the alpha-methine bridge. Seems to be specific for pheide a. Belongs to the chlorophyll catabolic enzymes (CCEs) (537 aa)
0.968
CH1
Pheophorbide a oxygenase family protein with Rieske [2Fe-2S] domain; Encodes chlorophyllide a oxygenase which converts chlorophyllide a to chlorophyllide b by catalyzing two successive hydroxylations at the 7-methyl group of chlorophyllide a . Mutants are deficient in pigments that associate with thylakoid membrane proteins, lacking chlorophyll b and light-harvesting proteins of photosystem II. The protein was shown through cross-linking experiments to interact with Toc75, Toc34, Tic40, Tic20 and Tic22 (536 aa)
