Patent abstract
We disclose a PS4 variant polypeptide derivable from a parent polypeptide, the parent polypeptide having non-maltogenic exoamylase activity, which PS4 variant polypeptide comprises one or more of the following substitutions: G69P, A141P, G223A, A268P, G313P, S399P and G400P, with reference to the position numbering of a Pseudomonas saccharophilia exoamylase sequence shown as SEQ ID NO: 1. Such PS4 variant polypeptides may be used as exo-amylases, particularly as non-maltogenic exoamylases. Combinations of such PS4 variant polypeptides together with Novamyl are disclosed.
