In enzymology, a 4-methyloxaloacetate esterase (EC 3.1.1.44) is an enzyme that catalyzes the chemical reaction
- oxaloacetate 4-methyl ester + H2O oxaloacetate + methanol
Thus, the two substrates of this enzyme are oxaloacetate 4-methyl ester and H2O, whereas its two products are oxaloacetate and methanol.
This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is oxaloacetate-4-methyl-ester oxaloacetohydrolase.
