    Abstract: A protein (I) with butynol I esterase (BIE) activity comprising at least one of 4 partial sequence polypeptides (S1-4) and their functional equivalents, is new. A protein (I) with butynol I esterase (BIE) activity comprises at least one of 4 partial sequence polypeptides (S1-4) and their functional equivalents. Independent claims are also included for the following: (1) polynucleotides (II) that encode (I), and complementary polynucleotides and sequences that hybridize to them; (2) an expression cassette (EC) comprising at least one (II), operably linked to regulators; (3) a recombinant vector for transforming eukaryotic or prokaryotic hosts, containing (II) or EC; (4) preparation of (I) by culturing organisms that produce (I), either endogenously or after transformation; (5) (I) produced by the method in (4); Pseudomonas glumae Lu2023 (DSM 13176), or its variants or mutants; (6) microorganisms containing the vector of (4); (7) method for enantioselective ester hydrolysis or transesterification using (I); and (8) optically active alcohols, carboxylic acids or esters prepared using (I).
