CYCLODEXTRIN GLYCOSYL TRANSFERASES FOR PRODUCING PRODUCING GAMMA-CYCLODEXTRIN

摘要

CGase produces gamma-CD up to an increased amount when starch or starch analog is converted to CD (Cyclodextrin) and at least 60% of the specific CGase activity of the starting CGase used in the preparation of the related enzymes. Wherein the amino acid sequence differs from the amino acid sequence of a known CGtaze by deletion of at least one amino acid in the region from amino acid position 155 to amino acid position 195, wherein position 1 of the protein sequence is Initiation of a signal peptide and its deletion increase the gamma-CGtase activity of the protein.
