The relationship between protein motions and catalytic activity is of contemporary interest in enzymology.
WebEnzyme Active Site and Substrate Specificity Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.
WebNov 3, 2016 · This interaction occurs, first forming an enzyme-substrate (ES) complex, in a part of the protein molecule (proteins are typically much larger than their substrates) called the active site. The features of active sites are described further below. Another characteristic of enzymes is their substrate specificity.
