KEGG ENZYME: 1.17.7.2

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.
