COMMENTARY 
LITERATURE
evolution
in contrast to benzoic acid carboxyl methyltransferase (BAMT) and benzoic acid/salicylic acid carboxyl methyltransferase (EC 2.1.1.274/2.1.1.273), MBMT also displays activity towards both benzoic acid and jasmonic acid. Phylogenetic analysis reveals that loquat MBMT forms a monophyletic group with jasmonic acid carboxyl methyltransferases (JMTs, EC 2.1.1.141) from other plant species. Plant enzymes with same BAMT activity have evolved independently
metabolism
it appears likely that a para-hydroxyl group of p-hydroxybenzoic acid is first methylated by an yet unidentified O-methyltransferase, then EjMBMT converts the resulting p-methoxybenzoic acid to methyl 4-methoxybenzoate in vivo, but not vice versa
physiological function
EjMT1 encodes a p-methoxybenzoic acid carboxyl methyltransferase (MBMT), an enzyme capable of converting p-methoxybenzoic acid to methyl p-methoxybenzoate via methylation of the carboxyl group. 4-Methoxybenzaldehyde and methyl 4-methoxybenzoate, along with (2-nitroethyl) benzene, are major components of the floral scent of the Japanese loquat (Eriobotrya japonica).
