Abstract

Aeropyrum pernix esterase (APE1547) was successfully used to catalyze the enantioselective transesterification of (R/S)-2-methyl-1-butanol in an ionic liquid (IL). Effects of various reaction conditions on the synthetic activity of the enzyme as well as enantioselectivity, including the type of IL, acyl donor, temperature, water activity, and substrate molar ratio were inverstigated. APE1547 showed good catalytic performance (activity > 0.8 μmol/min/mg, E > 25), and the enzyme-IL mixture was recycled five times with only a slight decrease in catalytic performance.
