KEGG   ENZYME: 1.17.7.2
Entry
EC 1.17.7.2                 Enzyme                                 
Name
7-hydroxymethyl chlorophyll a reductase;
HCAR;
71-hydroxychlorophyll-a:ferredoxin oxidoreductase
Class
Oxidoreductases;
Acting on CH or CH2 groups;
With an iron-sulfur protein as acceptor
Sysname
chlorophyll-a:ferredoxin oxidoreductase
Reaction(IUBMB)
chlorophyll a + H2O + 2 oxidized ferredoxin = 71-hydroxychlorophyll a + 2 reduced ferredoxin + 2 H+ [RN:R09071]
Reaction(KEGG)
R09071
Substrate
chlorophyll a [CPD:C05306];
H2O [CPD:C00001];
oxidized ferredoxin [CPD:C00139]
Product
71-hydroxychlorophyll a [CPD:C18151];
reduced ferredoxin [CPD:C00138];
H+ [CPD:C00080]
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. It similarly reduces chlorophyllide a.
