摘要：
A variant polypeptide having chymosin activity, wherein the variant has an amino acid sequence which, when aligned with the chymosin comprising the sequence set out in SEQ ID NO: 2, comprises at least one substitution of an amino acid residue corresponding to any of amino acids 2, 22, 40, 48, 50, 51, 53, 61, 62, 76, 88, 98, 99, 109, 112, 117, 125, 126, 135, 144, 160, 161, 163, 187, 189, 194, 200, 201, 202, 203, 221, 223, 240, 242, 244, 254, 267, 271, 273, 278, 280, 284, 289, 292, 294 or 295 said positions being defined with reference to SEQ ID NO: 2 and wherein the variant has one or more altered properties as compared with a reference polypeptide having chymosin activity. Such a variant polypeptide may be used in the preparation of a cheese.
