Flowchart presenting the actions of an endo-cellulase. The actions are: adsorption onto the cellulose surface (ADSORB), breaking hydrogen bonds (BREAK H. Bs.), hydrolyzing the glycosidic bond (CLEAVE Glyc. B.), and desorption from the cellulose (DESORB). Green rectangles denote chemical reactions (events) and orange ellipses denote branching points. Abbreviations: ‘Glyc. B.’ covalent glycosidic bond; ‘H. Bs.’ hydrogen bonds; ‘nrHB’ number of hydrogen bonds present between the monomers covered by the cellulase.
