We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | [https://www.uniprot.org/uniprot/XYNB_PAEBA XYNB_PAEBA] Plays a role in plant xylan biodegradation, probably via the hydrolysis of short xylooligosaccharides resulting from extracellular xylan hydrolysis, once they have been transported inside cells. Shows similar activity on xylans of different rate of arabinose or methylglucuronic substitution. Also displays high activity on aryl-xylosides. Is active on xylotetraose and xylotriose, but does not hydrolyze xylobiose, indicating that XynB is a xylanase and not a beta-xylosidase.<ref>PMID:12698280</ref> <ref>PMID:8998999</ref> | ||
