General annotation (Comments)

Function

Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose. Ref.1 Ref.2

Catalytic activity

Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.

Pathway

Glycan degradation; xylan degradation.

Subcellular location

Secreted Ref.1.

Induction

Expressed in the presence of D-xylose under conditions of alkaline ambient pH, probably under the regulation of the pacC transcription factor. Repressed in presence of glucose through the action of the creA transcription repressor. Ref.5 Ref.7 Ref.8

Biotechnological use

An increase in fruity aroma was organoleptically detected in the wine produced by the recombinant wine yeast strain T73 expressing xnlA. Ref.6

Sequence similarities

Belongs to the glycosyl hydrolase 11 (cellulase G) family.

Biophysicochemical properties

pH dependence:

Optimum pH is 5.4. Ref.2

Temperature dependence:

Optimum temperature is 52 degrees Celsius.
