[Ability of cellulases to degrade crystalline cellulose as a result of their effective adsorption on the substrate: experimental confirmation and theoretical interpretation]. / Sposobnost' tselliulaz k degradatsii kristallicheskoi tselliulozy kak rezul'tat ikh éffektivnoi adsorbtsii na substrate: éksperimental'noe podtverzhdenie i teoreticheskaia interpretatsiia.

It was shown experimentally that the increase in the adsorption ability of cellulases leads to a sharp increase of the rate of the enzymatic degradation of crystalline cellulose. At the same time the rate of degradation of amorphous cellulose does not depend on the adsorption ability of cellulases. These effects have been explained using a model which takes into consideration the influence of the structure of the solid substrate on the surface mobility of the adsorbed molecules of the enzyme. The equations were derived which inter-relate the catalytic and the adsorptive properties of cellulases.
