Accepted name: protein-glutamate methylesterase

Reaction: protein L-glutamate O5-methyl ester + H2O = protein L-glutamate + methanol

Other name(s): chemotaxis-specific methylesterase; methyl-accepting chemotaxis protein methyl-esterase; CheB methylesterase; methylesterase CheB; protein methyl-esterase; protein carboxyl methylesterase; PME; protein methylesterase

Systematic name: protein-L-glutamate-O5-methyl-ester acylhydrolase

Comments: Hydrolyses the products of EC (protein-L-isoaspartate(D-aspartate) O-methyltransferase), EC (isoorientin 3'-O-methyltransferase), EC (protein-glutamate O-methyltransferase) and EC (protein-S-isoprenylcysteine O-methyltransferase).
