From: Polysaccharide monooxygenase-catalyzed oxidation of cellulose to glucuronic acid-containing cello-oligosaccharides

Fig. 9

Proposed conversion of cellulose to glucuronic acid-containing cello-oligosaccharides by HiPMO1. HiPMO1 oxidizes the primary alcohol group at C-6 of cellulose to the aldehyde group and the carboxylic group (ROH → RCHO → RCOOH). The resulting glucuronic acid-containing cello-oligosaccharides might be further cleaved via hydrolysis by beta-glucuronidase (GUS) and beta-glucosidase (BGL) to yield glucose, glucuronic acid, and saccharic acid, and cleaved via beta-elimination by PL to produce unsaturated cello-oligosaccharides
