Schematic representation of hypothetical degradation of wildrice cell wall polysaccharides by CAZymes.

A. Degradation of cellulose by cellulolytic enzymes: endo-β-1,4-glucanase, cellobiohydrolase, β-glucosidase, and lytic polysaccharide monooxygenase; B. Degradation of hemicellulose polysaccharides and substituted residues by hemicellulolytic enzymes. Xylan: endoxylanase, β-xylosidase, acetylxylan esterase, feruloyl esterase, α-L-arabinofuranosidase, α-glucuronidase; Xyloglucan: endo-β-1,4-endoglucanase, α-L-fucosidase, β-galactosidase, α-xylosidase; Galactomannan: endo-β-1,4-mannanase, β-mannoside, α-galactosidase. C. Degradation of pectin polysaccharides and substituted moieties by pectinolytic enzymes. Homogalacturonan: endo- and exopolygalacturonase, pectin and pectate lyase, pectin acetylesterase, pectin methylesterase; Xylogalacturonan: endo- and exogalacturonase, β-xylosidase; Rhamnogalacturonan: rhamnogalacturonase, rhamnogalacturonan lyase, rhamnogalacturonan acetylesterase, α-L-rhamnosidase, β-1,4-galactosidase, β-1,4-galactanase, β-glucuronidase, α-L-arabinofuranosidase, α-L-arabinanase, β-1,6-galactosidase, β-1,3-galactanase α-L-fucosidase. The glycan symbol nomenclature used was according to [85].
