    摘要: A cyclodextrin glycosyltransferase (CGTase) which, in the conversion of starch or starch-like substrates to CD, produces .gamma.-CD in an increased amount, and whose protein sequence, in the region between amino acid position 180 and amino acid position 240, contains the amino acid sequence (SEQ ID NO: 1), where position 1 of the protein sequence is the beginning of the signal peptide of the CGTase and Xxx denotes a natural amino acid.
