An esterase from Bacillus subtilis (BS2) and itsdoublemutant E188W/M193C quickly hydrolyze n-butyl, n-propyl, methoxyethyl and allyl esters. The wild-type BS2 preferentially removes such esters from the γ-position of glutamate diesters, while the engineered enzyme has a reversed selectivity removing esters from the α-position of glutamate diesters.
