Methylesterase shown to have carboxylesterase activity, methyl indole-3-acetic acid (MeIAA) esterase activity and methyl jasmonate (MeJA) esterase activity in vitro. H2O + methyl (indol-3-yl)acetate = (indol-3-yl)acetate + H(+) + methanol H2O + methyl (-)-jasmonate = H(+) + jasmonate + methanol Plant hormone biosynthesis. Lipid metabolism; oxylipin biosynthesis. Belongs to the AB hydrolase superfamily. Methylesterase family.
