ABSTRACT:
A polypeptide possessing isoamylase activity with a revealed amino acid sequence. The polypeptide has features that it acts on amylaceous substances to produce a high-maltose content product, and that it has a molecular weight of 80,000.+-.5,000 daltons on SDS-polyacrylamide gel electrophoresis, as well as having an isoelectric point of 4.7.+-.0.1 on polyacrylamide gel isoelectric electrophoresis.
The polypeptide can be advantageously used in the industrial manufacture of starch syrups.
