Biochem/physiol Actions
Xylanase is a member of a family of glycoside hydrolases responsible for the breakdown of xylan in plants by cleaving the β 1,4 backbone.
Physical form
Supplied as a solution in 50 mM Tris-HCl, pH 7.5, 100 mM NaCl, and 25% glycerol.
Other Notes
One unit will produce 1 μmole of reducing sugar (measured as xylose) from xylan per minute at pH 5.8 at 70 °C.

Xylanases are hydrolytic enzymes which randomly cleave the beta 1,4 backbone of the complex plant cell wall polysaccharide xylan. Diverse forms of these enzymes exist, displaying varying folds, mechanisms of action, substrate specificities, hydrolytic activities (yields, rates and products) and

Multifunctional enzyme engineering can improve enzyme cocktails for emerging biofuel technology. Molecular dynamics through structure-based models (SB) is an effective tool for assessing the tridimensional arrangement of chimeric enzymes as well as for inferring the functional practicability before experimental validation.

Xylanase II from Trichoderma reesei catalyzes the hydrolysis of glycosidic bonds in xylan. Crystallographic studies of this commercially important enzyme have been initiated to investigate its reaction mechanism, substrate binding and dependence on basic pH conditions. The wild-type protein was

During rice blast fungal attack, plant xylanase inhibitor proteins (XIPs) that inhibit fungal xylanase activity are believed to act as a defensive barrier against fungal pathogens. To understand the role of XIPs in rice, a xylanase inhibitor was cloned from

An endoxylanase gene (PoxynA) that belongs to the glycoside hydrolase (GH) family 11 was cloned from a xylanolytic strain, Penicillium oxalicum B3-11(2). PoxynA was overexpressed in Trichoderma reesei QM9414 by using a constitutive strong promoter of the encoding pyruvate decarboxylase
