-
the enzyme hydrolyzes methyl-alpha-D-glucuronic acid side chains from the internal regions of xylan. The enzyme is required to undergo a substantial conformational change to form a productive Michaelis complex with glucuronoxylan

-
the role of the glucuronidase, in combination with cell-associated xylanases could be to hydrolyze decorated xylooligosaccharides, generated by extracellular hemicellulases, to xylose and 4-O-methyl-D-glucuronic acid, enabling the pseudomonad to preferentially utilize the sugars derived from these polymers
