-
The structure of Clostridium thermocellum endoglucanase CelC, a member of, the largest cellulase family (family A), has been determined at 2.15 A, resolution. The protein folds into an (alpha/beta)8 barrel, with a deep, active-site cleft generated by the insertion of a helical subdomain. The, structure of the catalytic core of xylanase XynZ, which belongs to, xylanase family F, has been determined at 1.4 A resolution. In spite of, significant differences in substrate specificity and structure (including, the absence of the helical subdomain), the general polypeptide folding, pattern, architecture of the active site and catalytic mechanism of XynZ, and CelC are similar, suggesting a common evolutionary origin.
