    摘要： The present invention relates to a polynucleotide encoding an enzyme having carboxyl esterase [E.C. 3.1.1.1] activity, wherein the coding sequence is selected from the group consisting of (a) a polynucleotide encoding an amino acid sequence as depicted in any one of SEQ ID NOs: 2, 4, 6 and 8; (b) a polynucleotide having or comprising a nucleotide sequence encoding an enzyme, wherein the nucleic acid sequence is as shown in any one of SEQ ID NOs: 1, 3, 5 and 7; (c) a polynucleotide having or comprising a nucleotide sequence encoding a fragment or derivative of an enzyme encoded by a polynucleotide of (a) or (b), wherein in said derivative one or more amino acid residues are conservatively substituted compared to the amino acid sequence of (a); (d) a polynucleotide encoding an enzyme having carboxyl esterase activity which polynucleotide is at least 65% identical to a polynucleotide encoding an enzyme as shown in one of SEQ ID NOs: 2, 4, 6 and 8; (e) a polynucleotide having or comprising a nucleotide sequence the complementary strand of which hybridizes to a polynucleotide as defined in any one of (a) to (d); and (f) a polynucleotide having or comprising a nucleotide sequence being degenerate to the nucleotide sequence of the polynucleotide of (d) or (e); or the complementary strand of such a polynucleotide of (a) to (f) or fragments thereof useful as specific probes or primers. The present invention also relates to a host, genetically engineered with the polynucleotide of the present invention or the vector of the present invention. The present invention also relates to a polypeptide comprising the amino acid sequence encoded by a polynucleotide of the present invention or which is obtainable by the process of the present invention. Moreover, the present invention relates to a process for producing said polypeptide and for producing bacteria expressing said polypeptide. Finally, the present invention relates to a composition comprising the polynucleotide of the present invention, the vector of the present invention, the host of the present invention, the polypeptide of the present invention, the antibody of the present invention and/or one or more primers of the present invention.
