Popis:	35 metagenome-derived esterases bearing a GGG(A)X motif were screened for activity and enantioselectivity in the hydrolysis of a range of tertiary alcohol acetates. Most of the active esterases showed little or no enantioselectivity in the hydrolysis of the terpinyl acetate, linalyl acetate and 3-methylpent-1-yn-3-yl acetate. However, one esterase showed excellent enantioselectivity (E > 100) in the kinetic resolution of 1,1,1-trifluoro-2-phenylbut-3-yn-2-yl acetate as confirmed by a preparative scale reaction.
