Nucleotide sequence of the beta-cyclodextrin glucanotransferase gene of alkalophilic Bacillus sp. strain 1011 and similarity of its amino acid sequence to those of alpha-amylases.

摘要

The nucleotide sequence of the gene for cyclodextrin glucanotransferase of alkalophilic Bacillus sp. strain 1011 was determined. The deduced amino acid sequence at the NH2-terminal side of the enzyme showed a high homology with the sequences of alpha-amylase in the three regions which constitutes the active centers of alpha-amylases.
