Protein

Bifunctional xylanase/deacetylase

Gene

xyn11A

Organism
Pseudobutyrivibrio xylanivorans
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Endo-acting xylanase which specifically cleaves internal linkages on the xylan backbone, releasing xylooligosaccharides. Is also probably able, via its C-terminal domain, to remove acetyl groups from acetylated xylan, and thus it is probably capable of hydrolyzing acetylated xylan.1 Publication

Catalytic activityi

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

pH dependencei

Optimum pH is 5.6. Active from pH 4.0 to 8.0.

Temperature dependencei

Optimum temperature is 38 degrees Celsius.
