It is necessary to have also in a look that a substratum molecule though it, as a rule, also is much less than enzyme molecule, too possesses some mobility and at interaction with enzyme this mobility can promote fuller compliance.
In the first reaction under the influence of enzyme of an oxidase there is an oxidation of amino acids. Thus an amino group (NH separates in the form of ammonia (NH and connection is formed, containing kretonny group (S=O) and called by the ketokisloty.
Rather group specificity is shown when enzyme is indifferent to structure of connection and only the communication type matters. The chymotrypsin splitting only peptide communication is an example.
