  • GLUCOAMYLASE AND METHODS OF USE THEREOF
    Publication number: 20230340444
    Abstract: Described are a recombinant host cell, a composition comprising a glucoamylase and methods of saccharifying the starch substrate using the glucoamylase. Moreover, the disclosure also relates to a process of producing fermentation products and a method for increasing starch digestibility in an animal as well as a method of producing a fermented beverage. The glucoamylase or 1,4-alpha-D-glucan glucohydrolase (EC 3.2.1.3) is preferably from the Mucorales-clade, especially having high sequence identity to the glucoamylase from Saksenaea vasiformis.

  • PROTEIN HYDROLYSATES WITH INCREASED YIELD OF N-TERMINAL AMINO ACID
    Publication number: 20220136027
    Abstract: The present invention related to a method for preparing a protein hydrolysate from a proteinaceous material by contacting the material with a proteolytic enzyme mixture having a proline specific exopeptidase. In particular, the proline specific exopeptidase is an aminopeptidase specific for at the five amino acid N-terminal sequence X-Pro-Gln-Glv-Pro-, where X is any amino acid. The present invention also relates to use of the aminopeptidase with a second exopeptidase and an endopeptidase.
