Entry
EC 1.17.7.2                 Enzyme                                 

Name
7-hydroxymethyl chlorophyll a reductase;
HCAR
Class
Oxidoreductases;
Acting on CH or CH2 groups;
With an iron-sulfur protein as acceptor
BRITE hierarchy
Sysname
71-hydroxychlorophyll-a:ferredoxin oxidoreductase
Reaction(IUBMB)
71-hydroxychlorophyll a + 2 reduced ferredoxin + 2 H+ = chlorophyll a + 2 oxidized ferredoxin + H2O [RN:R09071]
Reaction(KEGG)
Substrate
71-hydroxychlorophyll a;
reduced ferredoxin [CPD:C00138];
H+ [CPD:C00080]
Product
chlorophyll a [CPD:C05306];
oxidized ferredoxin [CPD:C00139];
H2O [CPD:C00001]
Comment
Contains FAD and an iron-sulfur center. This enzyme, which is present in plant chloroplasts, carries out the second step in the conversion of chlorophyll b to chlorophyll a (cf. EC 1.1.1.294, chlorophyll(ide) b reductase). It similarly reduces chlorophyllide a.
History
EC 1.17.7.2 created 2011
Pathway
Porphyrin and chlorophyll metabolism
Metabolic pathways
Biosynthesis of secondary metabolites
