HUMICOLA INSOLENS ENDOCELLULASE EGI NATIVE STRUCTURE
Overview
Cellulose is the major polysaccharide component of the plant cell wall and, the most abundant naturally produced macromolecule on Earth. The enzymic, degradation of cellulose, by cellulases, is therefore of great, environmental and commercial significance. Cellulases are found in 12 of, the glycoside hydrolase families classified according to their amino acid, sequence similarities. Endoglucanase I (Cel7B), from the soft-rot fungus, Humicola insolens, is a family 7 enzyme. The structure of the native form, of Cel7B from H. insolens at 2.2 A resolution has been solved by molecular, replacement using the known Trichoderma reesei cellobiohydrolase I [Divne, Stahlberg, Reinikainen, Ruohonen, Pettersson, Knowles, Teeri and Jones, (1994) Science 265, 524-528] structure as the search model. ...
