Structural highlights

5hk8 is a 6 chain structure with sequence from Arath. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:PPD, MES16, At4g16690, dl4370c, FCAALL.12 (ARATH)
Activity:Pheophorbidase, with EC number 3.1.1.82
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

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]
