: retaining anomeric configuration (see R00026)
: The enzymatic hydrolysis of cellulose involves three types of cellulases (endoglucanases, exoglucanases and β-glucosidases) working in synergy. Endoglucanases (EC 3.2.1.4) randomly cleave the β-1,4 glycosidic linkages of cellulose; Exoglucanases (such as cellobiohydrolases, |FRAME: 3.2.1.91-RXN EC 3.2.1.91"|) attack cellulose chain ends to produce the constitutive unit of cellulose, cellobiose (a dimer of glucose linked by a β-1,4 glycosidic bond); and β-glucosidases (EC 3.2.1 21) hydrolyse cellobiose into two molecules of glucose.
