Catalysis of the incorporation of one atom from molecular oxygen into a compound and the reduction of the other atom of oxygen to water. Catalysis of hydroxylation at the 7-methyl group of chlorophyllide a, according to the reactions: chlorophyllide a + O2 + NADPH + H+ = 7-hydroxychlorophyllide a + H2O + NADP+ and 7-hydroxychlorophyllide a + O2 + NADPH + H+ = chlorophyllide b + 2 H2O + NADP+. Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from one donor, and one oxygen atom is incorporated into a donor. Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from one donor, and molecular oxygen is incorporated into a donor.
