Macromolecules, mostly of protein nature, that function as @[email protected] by increasing the reaction rates. In general, an enzyme catalyses only one reaction type (reaction specificity) and operates on only one type of @[email protected] (substrate specificity). Substrate molecules are attacked at the same site (regiospecificity) and only one or preferentially one of the enantiomers of @[email protected] substrates or of @[email protected] mixtures is attacked (stereospecificity).
