ENZYME entry: EC 1.14.13.122

Accepted Name
Chlorophyllide a oxygenase.
Alternative Name(s)
CAO.
Cholorophyll-b synthase.
Reaction catalysed
Chlorophyllide a + 2 O(2) + 2 NADPH <=> chlorophyllide b + 3 H(2)O + 2 NADP(+)
Cofactor(s)
Fe cation.
Comment(s)
  • Catalyzes two successive hydroxylations at the 7-methyl group of chlorophyllide a.
  • The second step yields the aldehyde hydrate, which loses H(2)O spontaneously to form chlorophyllide b.
  • Chlorophyll a and protochlorophyllide a are not substrates.
  • Formerly EC 1.13.12.14.
