CC -!- FUNCTION: Methylesterase shown to have carboxylesterase activity,
CC methyl indole-3-acetic acid (MeIAA) esterase activity, methyl
CC salicylate (MeSA) esterase activity and methyl jasmonate (MeJA)
CC esterase activity in vitro. Required to convert methyl salicylate
CC (MeSA) to salicylic acid (SA) as part of the signal transduction
CC pathways that activate systemic acquired resistance in systemic tissue.
CC MeSA is believed to be an inactive form that needs to be demethylated
CC to exert a biological effect. {ECO:0000269|PubMed:18467465,
CC ECO:0000269|PubMed:18643994}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + methyl (indol-3-yl)acetate = (indol-3-yl)acetate + H(+)
CC + methanol; Xref=Rhea:RHEA:32919, ChEBI:CHEBI:15377,

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:33612;
CC Evidence={ECO:0000269|PubMed:18467465};
CC -!- ACTIVITY REGULATION: Esterase activity is down-regulated by salicylic
CC acid (SA). {ECO:0000269|PubMed:18643994}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=57.3 uM for methyl salicylate (MeSA)
CC {ECO:0000269|PubMed:18643994};
CC Vmax=28.92 nmol/min/ug enzyme with methyl salicylate (MeSA) as
CC substrate {ECO:0000269|PubMed:18643994};
CC -!- PATHWAY: Plant hormone biosynthesis. {ECO:0000269|PubMed:18467465}.
CC -!- PATHWAY: Lipid metabolism; oxylipin biosynthesis.
CC {ECO:0000269|PubMed:18467465}.
CC -!- INDUCTION: By pathogen infection. {ECO:0000269|PubMed:18643994}.
CC -!- MISCELLANEOUS: Expression of MES1 can restore systemic acquired
CC resistance in SAR-deficient tobacco plants.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Methylesterase
CC family. {ECO:0000305}.
