Cytochrome P450 CYP89A9 catalyzes a novel route in chlorophyll breakdown. Chlorophyll (green) is sequentially broken down into fluorescent catabolites (blue) including FCC, which is converted to FDCC by CYP89A9 (red). FCC and FDCC are non-enzymatically converted into non-fluorescent catabolites (black) NCC and NDCC, respectively. [Modified from Christ et al., 2013; Figure 1]
