1. In some cases, the cofactor completes the active site of the enzyme or modifies it in such a manner that substrate binding can ensue. 2. The cofactor acts as a donor of electrons or atoms to the substrate and following the reaction is returned to its former state.
Enzyme structures may also contain allosteric sites where the binding of a small molecule causes a conformational change that increases or decreases activity. A small number of RNA-based biological catalysts called ribozymes exist, which again can act alone or in complex with proteins. The most common of these is the ribosome which is a complex of protein and catalytic RNA components.
