NATIVE XYLANASE10C FROM CELLVIBRIO JAPONICUS
Overview
Microbial degradation of the plant cell wall is the primary mechanism by, which carbon is utilized in the biosphere. The hydrolysis of xylan, by, endo-beta-1,4-xylanases (xylanases), is one of the key reactions in this, process. Although amino acid sequence variations are evident in the, substrate binding cleft of "family GH10" xylanases (see, afmb.cnrs-mrs.fr/CAZY/), their biochemical significance is unclear. The, Cellvibrio japonicus GH10 xylanase CjXyn10C is a bi-modular enzyme, comprising a GH10 catalytic module and a family 15 carbohydrate-binding, module. The three-dimensional structure at 1.85 A, presented here, shows, that the sequence joining the two modules is disordered, confirming that, linker sequences in modular glycoside hydrolases are highly flexible., CjXyn10C hydrolyzes ...
