Comments
  • FUNCTION: Catalyzes a two-step oxygenase reaction involved in the synthesis of chlorophyll b. Acts specifically on the non-esterified chlorophyllide a and not on chlorophyll a.
  • CATALYTIC ACTIVITY: Chlorophyllide a + O2 + NADPH = 7-hydroxychlorophyllide a + H2O + NADP+.
  • CATALYTIC ACTIVITY: 7-hydroxychlorophyllide a + O2 + NADPH = chlorophyllide b + 2 H2O + NADP+.
  • SUBCELLULAR LOCATION: Plastid, chloroplast inner membrane; Peripheral membrane protein. Plastid, chloroplast thylakoid membrane; Peripheral membrane protein (By similarity).
  • SIMILARITY: Contains 1 Rieske domain.
