| Enzyme Function | FUNCTION: Endo-acting xylanase which specifically cleaves internal linkages on the xylan backbone, releasing xylooligosaccharides. Is able to hydrolyze oat spelt xylan, the arabinoxylans from wheat and rye, and glucuronoxylan. Also displays very low activity against xylooligosaccharides. During the xylan degradation process, Xyn10C may act on the soluble xylans and long xylooligosaccharides products released by the secreted xylanases Xyn11A, Xyn11B and Xyn10A. {ECO:0000269|PubMed:14670951, ECO:0000269|PubMed:7492333}. |
