CC -!- FUNCTION: Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a
CC major structural heterogeneous polysaccharide found in plant biomass
CC representing the second most abundant polysaccharide in the biosphere,
CC after cellulose. {ECO:0000269|PubMed:11999400}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.;
CC EC=3.2.1.8;
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=200 uM for birch wood xylan {ECO:0000269|PubMed:11999400};
CC Vmax=435 umol/min/mg enzyme {ECO:0000269|PubMed:11999400};
CC pH dependence:
CC Optimum pH is 5.5. Retain 85 percent of its activity in the pH range
CC from 6.0 to 7.0 after a 12 h incubation at 25 degrees Celsius.
CC {ECO:0000269|PubMed:11999400};
CC Temperature dependence:
CC Optimum temperature is 58 degrees Celsius. The purified enzyme showed
CC complete stability under 60 degrees Celsius.
CC {ECO:0000269|PubMed:11999400};
CC -!- PATHWAY: Glycan degradation; xylan degradation.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:11999400,
CC ECO:0000269|PubMed:16672490}.
CC -!- MISCELLANEOUS: The promoter does not contain any 5'-GGCTAAA-3' sequence
CC identified as binding sites for the xylanolytic transcriptional
CC activator xlnR.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 10 (cellulase F) family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAE56751.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
