Entry
EC 1.1.1.294                Enzyme                                 
Name
chlorophyll(ide) b reductase;
chlorophyll b reductase;
Chl b reductase
Class
Oxidoreductases;
Acting on the CH-OH group of donors;
With NAD+ or NADP+ as acceptor
Sysname
71-hydroxychlorophyllide-a:NAD(P)+ oxidoreductase
Reaction(IUBMB)
71-hydroxychlorophyllide a + NAD(P)+ = chlorophyllide b + NAD(P)H + H+ [RN:R08914 R08915]
Reaction(KEGG)
R08914 R08915;
(other) R09069 R09070
Substrate
71-hydroxychlorophyllide a;
NAD+ [CPD:C00003];
NADP+ [CPD:C00006]
Product
chlorophyllide b [CPD:C16541];
NADH [CPD:C00004];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
This enzyme carries out the first step in the conversion of chlorophyll b to chlorophyll a. It is involved in chlorophyll degradation, which occurs during leaf senescence [3] and it also forms part of the chlorophyll cycle, which interconverts chlorophyll a and b in response to changing light conditions [4,5].
