Fig. 6From: Enhancing the catalytic activity of a novel GH5 cellulase GtCel5 from Gloeophyllum trabeum CBS 900.73 by site-directed mutagenesis on loop 6Hydrogen bonds probably formed at position 233 within the complexes of GtCel5 or its variants and cellotetraose. The residue of position 233 is shown in purple, and the cellotetraose is shown in blue. a GtCel5. b N233A. c N233GBack to article page
