Cyclodextrin glycosyltransferases for producing gamma-cyclodextrin

摘要

The invention relates to cyclodextrin glycosyltransferases which in the conversion of starch or starch-like substrates to CD produce gamma -CD to an increased extent, 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 Xxx Asp, where position 1 of the protein sequence is the start of the signal peptide of CGTase and Xxx is a natural amino acid.
