Gene encodes for the enzyme chlorophyllase which catalyzes the first step of chlorophyll degradation by dephytylation of chlorophyll a to chlorophyllide. IT is a homolog of Arabidopsis CLH2 (AT5G43860) gene. The protein lacks any predicted plastid targeting signal peptide with a significant score, however based on the homology to Arabidopsis CHL2, it is predicted to be localized to plastid.
