Hydrolyzes various short-chain esters, such as triacylglycerols and vinyl esters. Has no activity against emulsified substrates. a carboxylic ester + H2O = a carboxylate + an alcohol + H(+) a propanoate ester + H2O = an aliphatic alcohol + H(+) + propanoate 1,2,3-tripropanoylglycerol + H2O = dipropanoylglycerol + H(+) + propanoate a butanoate ester + H2O = an aliphatic alcohol + butanoate + H(+) an acetyl ester + H2O = acetate + an aliphatic alcohol + H(+) 1,2,3-tributanoylglycerol + H2O = butanoate + dibutanoylglycerol + H(+) Strongly inhibited by diethyl paranitrophenyl phosphate, which is a specific inhibitor of serine hydrolases. Optimum pH is 7.0-8.0. Optimum temperature is 45 degrees Celsius. Monomer. Remains active in dormant M.tuberculosis. Belongs to the 'GDXG' lipolytic enzyme family.
