A method for making an isolated chymosin polypeptide variant comprising the steps: (a): making an alteration at one or more positions in a parent polypeptide having chymosin activity, wherein the alteration is comprising a substitution, a deletion or an insertion in at least one amino acid position corresponding to position 70; and (b): producing and isolating the altered polypeptide of step (a) and thereby obtaining the isolated chymosin polypeptide variant, wherein the variant has chymosin activity; and wherein: (i): the amino acid position of the parent polypeptide is determined by an alignment of the parent polypeptide with the polypeptide of SEQ ID NO: 1 (bovine chymosin) - i.e. the polypeptide of SEQ ID NO: 1 is used to determine the corresponding amino acid sequence in the parent polypeptide; and (ii): the parent polypeptide has at least 90% sequence identity with the mature polypeptide of SEQ ID NO: 2 (Camel chymosin), which is from amino acid position 59 to amino acid position 381 of SEQ ID NO: 2; (iii): the isolated variant polypeptide has less than 100% sequence identity with the mature polypeptide of SEQ ID NO: 2 (camel chymosin); wherein the isolated chymosin polypeptide variant has: - a chymosin activity giving a higher C/P ratio as compared to the C/P ratio of bovine chymosin comprising the mature polypeptide of SEQ ID NO: 1; and - a chymosin activity giving a higher C/P ratio as compared to the C/P ratio of camel chymosin comprising the mature polypeptide of SEQ ID NO: 2; the isolated chymosin variant comprises less than 30 amino acid alterations as compared to the mature polypeptide of SEQ ID NO: 2 (camel chymosin); an insertion means adding 1-3 amino acids adjacent to an amino acid occupying a position.
