Ruxyn1 Glycosyl hydrolase (GH) family 43 b-Dxylosidase/a-L-arabinofuranosidase Ruxyn can hydrolyze p-nitrophenyl-b-D-xylopyranoside (pNPX), p-nitrophenyla-L-arabinofuranoside (pNPA), and xylo-oligosaccharide substrates. Ruxyn shows high synergism with endoxylanase,greatly elevating the reducing sugars released from brichwood xylans, and converted most intermediate xylo-oligosaccharide hydrolysate into xylose.


We construct the gene on the carrier displaying on the surface of Pichia pastoris and express it it in Pichia pastoris with electroporation. Then we detect the expression on the surface of Pichia pastoris by observing with fluorescent microscope and by flow cytometry analysis.

We fused FLAG-tag with N-terminal of Ruxyn gene on Ruxyn-pPIC9k vector. Label cells with Rabbit Anti Flag-Tag Polyclonal antibody and Goat Anti Rabbit RPE Polyclonal antibody. Result of flow cytometry analysis is as follows: fluorescence intensity x-mean value of Pichia pastoris with pPIC9k empty vector is 1.14, with Ruxyn-pPIC9k is 8.56.
