Chlorophyllide a reductase (original) (raw)

Chlorophyllide a reductase (EC 1.3.7.15), also known as COR, is an enzyme with systematic name bacteriochlorophyllide-a:ferredoxin 7,8-oxidoreductase. It catalyses the following chemical reaction chlorophyllide a + 2 reduced ferredoxin + ATP + H2O + 2 H+ 3-deacetyl 3-vinylbacteriochlorophyllide a + 2 oxidized ferredoxin + ADP + phosphate * Structure of the substrate and product of the enzyme * Chlorophyllide a * Bacteriochlorophyllide a (R=H). The product of COR retains the vinyl group of the substrate in place of the acetyl group shown
