Abstract: The present invention relates to a variant polypeptide having maltogenic alpha-amylase activity wherein the polypeptide comprises an amino acid sequence, which, when aligned with an amino acid sequence of SEQ ID NO: 1, comprises an amino acid substitution F188L/I, S200N, and D261G, and optionally a further amino acid substitution T288P, wherein the amino acid substitutions are determined with reference to SEQ ID NO: 1, and wherein the polypeptide has an amino acid sequence which has at least 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or at least 99% identity to the amino acid sequence of SEQ ID NO: 1. The invention also relates to a process for the preparation of a dough or a baked product wherein the variant polypeptide is used.
