ACIDIC THERMOPHILIC POLYGALACTURONASE TEPG28A, AND ENCODING GENE AND APPLICATION THEREOF

摘要

Provided are acidic thermophilic polygalacturonase TePG28A, encoding gene and application thereof. The amino acid sequence thereof is as shown in SEQ ID NO. 1 or SEQ ID NO. 2. The expressed acidic thermophilic polygalacturonase by means of cloning has advantages such as high enzyme activity and high stability; can adapt to the high temperature environment in the industrial production; has better application prospect; and can effectively degrade pectic substances such as polygalacturonic acid and pectin; and can be effectively applied to the industrial field of feed, food, and textile, etc.
