  • MALTOTRIOSE-GENERATING AMYLASE
    Publication number: 20210388406
    Abstract: A maltotriose-generating amylase has an amino acid sequence of any one three polypeptides. One or more amino acids can be substituted, added, inserted, or deleted, such that the polypeptides have at least 70% sequence identity with the amino acid sequences of the polypeptides. The polypeptides are encoded by DNA, which can be included in recombinant vectors. Transformants can be obtained by transforming a host with the DNA.
