| chlorophyllide a + H2O | BciC demethoxycarbonylase removes the C13(2)-methoxycarbonyl group to facilitate the self-aggregation of BChl c. The substrate specificity of BciC is measurably affected by structural changes on the A/B rings including the bacteriochlorin pi-systems. Moreover, BciC shows its activity on a Zn-chelated chlorophyll derivative. On the contrary, BciC recognizes structural modifications on the D/E rings, including porphyrin pigments, which resulted in the significant decrease in the enzymatic activity | Chlorobaculum tepidum | 8-ethyl-12-methyl-3-vinyl-bacteriochlorophyllide d + methanol + CO2 | - |
