Cyclodextrin glycosyltransferase for the production of gamma-cyclodextrin.

摘要

The invention relates to cyclodextrin glycosyltransferases which produce gamma -CD to an increased extent in the conversion of starch or starch-like substrates into CD, characterised in that their protein sequence in the region between amino acid position 180 and amino acid position 240 contains the amino acid sequence Asn Leu Xaa Asp (SEQ. ID NO: 1), where position 1 of the protein sequence at the start of the signal peptide is CGTase and Xaa is a natural amino acid.
