ENZYME entry: EC 1.14.13.81

PURL: https://purl.expasy.org/enzyme/EC/1.14.13.81
Accepted Name
magnesium-protoporphyrin IX monomethyl ester (oxidative) cyclase
Alternative Name(s)
Mg-protoporphyrin IX monomethyl ester oxidative cyclase
Reaction catalysed
Mg-protoporphyrin IX 13-monomethyl ester + 3 NADPH + 3 O2 + 2 H(+) = 3,8-divinyl protochlorophyllide a + 3 NADP(+) + 5 H2O
Comment(s)
  • The enzyme participates in the biosynthesis of chlorophyllide a in aerobic organisms.
  • The same transformation is achieved in anaerobic organisms by EC 1.21.98.3.
  • Some facultative phototrophic bacteria, such as Rubrivivax gelatinosus, possess both enzymes.
