    摘要: The present invention relates to a method for preparing a variant lipolytic enzyme comprising expressing in a host organism a nucleotide sequence which has at least 90% identity with a nucleotide sequence encoding a fungal lipolytic enzyme and comprises at least one modification at a position which corresponds in the encoded amino acid sequence to a) the introduction of at least one glycosylation site in the amino acid sequence compared with the original fungal lipolytic enzyme; b) the introduction of at least one amino acid at a surface position and at a location in an external loop distal to the active site of the enzyme which is more hydrophilic; or c) a substitution or insertion at one or more of positions disclosed herein or a deletion at one or more positions disclosed herein. The invention also relates to polypeptide produced by the method and to novel nucleic acids.
