enzyme produces beta-xylose from beta-xylopyranosides while retaining the anomeric configuration of the xylose in the substrate. Enzyme shows transglycosylation activities in the presence of alcohols as acceptors. No substrate: 4-nitrophenyl-alpha-L-arabinofuranoside, 4-nitrophenyl-alpha-D-xylopyranoside, 4-nitrophenyl-alpha-D-glucopyranoside, and 4-nitrophenyl-beta-D-glucopyranoside, oat spelt xylan, birch wood xylan, or carboxymethyl cellulose

with use of vector pHsh, expression of XylC increases approximately 4fold when a loop within the translational initiation region in the mRNA is removed by site-directed mutagenesis. The increased expression of xylCm is due to removal of a stem-loop structure without a change of the amino acid sequence of the heterologously expressed enzyme
