Chimeric ß-glucosidase between Cellvibrio gilvus and Ruminococcus albus enzymes

Abstract

Based on homology search in the amino acid sequences, a chimeric ß-glucosidase with enzyme activity has been prepared by replacing C-terminal region of Thr509-Arg646 from Cellvibrio gilvus with N-terminal region of Arg160-Gly283 from Ruminococcus albus. The chimeric enzyme showed broader optimum pH and slightly higher heat stability compared with original C. gilvus enzyme.
