Abstract:
1. A non-naturally occurring PS4 variant polypeptide derivable from a parent polypeptide, the parent polypeptide having non-maltogenic exoamylase activity, which PS4 variant polypeptide comprises an alanine substitution at a position corresponding to position 223 of the Pseudomonas saccharophila exoamylase sequence of SEQ ID NO: 1, wherein the PS4 variant polypeptide has at least 95% sequence identity with the polypeptide of SEQ ID NO: 1 and non-maltogenic exoamylase activity and a higher thermostability compared to the parent polypeptide when tested under the same conditions, and which has a higher pH stability compared to the parent polypeptide when tested under the same conditions.
