Enzyme-Substrate (ES) complexes are formed during enzyme catalysed chemical reactions.
Every enzyme is equipt with a 'cleft' in its structure, which is complementary to a particular substrate. This is known as the active site. As well as shape, the specificity of the active site is developed further via the amino acid R-Groups within the site. These groups will interact specifically with the substrate molecule(s) [1]. The ES complex is the state in, which the active site of the enzyme is non-covalently bound to the substrate molecule(s). This is where the chemical reaction occurs.
ENZYME + SUBSTRATE -> ENZYME SUBSTRATE COMPLEX -> ENZYME + PRODUCT
