NCBI Protein Information
methyl esterase 16
NCBI Summary
Encodes a protein shown to have carboxylesterase activity, methyl IAA esterase activity, and methyl jasmonate esterase activity in vitro. This protein does not act on MeSA, MeGA4, or MEGA9 in vitro. Although MES16 is similar to MES17, a MeIAA hydrolase, two mes16 mutant lines (SALK_151578) and (SALK_139756) do not show altered sensitivity to MeIAA in root growth assays. MES16 transcripts appear to be more than 10-fold less abundant than those of MES17 in roots.

UniProt Comments
Involved in the chlorophyll breakdown by its action in fluorescent chlorophyll catabolites (FCCs) demethylation. Demethylates the C132-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.
