RT   "A bifunctional xylanase encoded by the xynA gene of the rumen
RT   cellulolytic bacterium Ruminococcus flavefaciens 17 comprises two
RT   dissimilar domains linked by an asparagine/glutamine-rich sequence.";
RL   Mol. Microbiol. 6:1013-1023(1992).
CC   -!- FUNCTION: Xylanase domain releases more xylo-oligosaccharides and
CC       GH10 domain more xylose.
CC   -!- CATALYTIC ACTIVITY: Endohydrolysis of (1->4)-beta-D-xylosidic
CC       linkages in xylans.
CC   -!- PATHWAY: Glycan degradation; xylan degradation.
CC   -!- SIMILARITY: In the N-terminal section; belongs to the glycosyl
CC       hydrolase 11 (cellulase G) family. {ECO:0000305}.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the glycosyl
CC       hydrolase 10 (cellulase F) family. {ECO:0000305}.
