Abstract

Official abstract text for this publication.

Disclosed are compositions and methods relating to variant alpha-amylases. The variant alpha-amylases are useful, for example, for starch liquefaction and saccharification, for cleaning starchy stains in laundry, dishwashing, and other applications, for textile processing (e.g., desizing), in animal feed for improving digestibility, and for baking and brewing.

First claim

Opening claim text (preview).

What is claimed is: 1. A recombinant variant α-amylase comprising an amino acid sequence having at least 97% amino acid sequence identity to the amino acid sequence of SEQ ID NO: 2, excluding the wild-type Amy707 enzyme having the amino acid sequence of SEQ ID NO: 2. 2. A composition for liquefying starch comprising the variant α-amylase of claim 1 . 3. A detergent composition comprising the variant α-amylase of claim 1 .
