摘要：
We describe a PS4 variant polypeptide derivable from a parent polypeptide having non-maltogenic exoamylase activity, in which the PS4 variant polypeptide comprises an amino acid mutation at one or more positions selected from the group consisting of: 121, 161, 223, 146, 157, 158, 198, 229, 303, 306, 309, 316, 353, 26, 70, 145, 188, 272, 339, with reference to the position numbering of a Pseudomonas saccharophilia exoamylase sequence shown as SEQ ID NO: 1.
