docking analysis of Rex8A with methyl-glucuronic acid branched oligomers. Mixtures containing the aldouronic acids 4-O-methyl-beta-D-glucuronosyl-(1->2)-beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranosyl-(1->4)-D-xylose (MeGlcA3Xyl3) (aldotetraouronic acid) and beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranosyl-(1->4)-[4-O-methyl-alpha-D-glucuronosyl-(1->2)]-beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranosyl-(1->4)-D-xylose (MeGlcA3Xyl5) (aldohexaouronic acid) are prepared from beechwood 4-O-methyl-D-glucuronoxylan by xylanase treatment. Aldotetraouronic acid MeGlcA3Xyl3 consists of a xylotriose with a methyl-glucuronic acid substituent in the third xylose from the reducing end. The cleavage of this substrate to xylose and to an aldouronic acid shortened by one residue indicates that Rex8A accommodates the methyl-glucuronic acid-substituted xylopyranosyl residue in the -2 subsite of the catalytic cleft of the enzyme. Ligand accommodation in the catalytic site, a xylotriose decorated with a 4-O-MeGlcA moiety at O2 of the third xylose from the reducing end (MeGlcA3Xyl3) is modeled into the active-site channel

the enzyme acts rapidly on the beta-anomer of beta-D-xylopyranosyl-(1-4)-beta-D-xylopyranosyl-(1-4)-beta-D-xylopyranose, leaving the new reducing end in the alpha configuration. It also acts on longer oligosaccharides that have this structure at their reducing ends. The penulimate residue must be xylose, but replacing either of the other two residues with glucose merely slows the rate greatly

physiological function
Halalkalibacterium halodurans
Rex8As are key enzymes in the efficient saccharification of heteroxylan into xylose, a major component of lignocellulosic substrates
physiological function
the enzyme is involved in depolymerization of glucuronoxylan, a major component of the lignocellulosic substrates. Rex8A is a reducing-end xylose-releasing exo-oligoxylanase that efficiently hydrolyzes xylose from neutral and acidic xylooligosaccharides generated by the action of other xylanases also secreted by the strain. The hydrolytic ability of Rex8A on branched oligomers can be crucial for the complete depolymerization of highly substituted xylans, which is indispensable to accomplish biomass deconstruction and to generate efficient catalysts
