Evidence for lysozyme-type mechanism of hydrolysis in xylanases.
In the last year several new xylanase three-dimensional structures were solved. Examination of these new structures in combination with recently obtained data from site-directed mutagenesis and kinetic analysis provided insights into the catalytic mechanism of xylanases. It is now possible to determine the type of mechanism by which xylanases hydrolyse a complex substrate such as xylan.
