Function
[PPD_ARATH] Involved in the chlorophyll breakdown by its action in fluorescent chlorophyll catabolites (FCCs) demethylation. Demethylates the C13(2)-carboxymethyl group present at the isocyclic ring of chlorophyll. Also able to catalyze pheophorbides in vitro. Methylesterase shown to have carboxylesterase activity, methyl indole-3-acetic acid (MeIAA) esterase activity and methyl jasmonate (MeJA) esterase activity in vitro.[1] [2]
