This invention relates to nucleic acids encoding amylase polypeptides, the encoded polypeptides and uses thereof. The amylases of the present invention have been engineered to have more beneficial qualities. Specifically, the amylases of the current invention show an altered exo-specificity and/or thermostability. Some embodiments of the invention relate to said polypeptides and nucleic acids and their uses as non-maltogenic exoamylases in producing food products.

Modified amylases, nucleic acids encoding those amylases and uses thereof

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.
