The interaction and docking of two molecules is the process by which chemical reactions occur on a biological level. One molecule either inserts itself or closely associates itself with another, and the resulting close association of the two molecules facilitates a particular biological function or cascade of events. For example, when long chains of amino acids, or polyproteins, are inserted into a cleft of HIV-1 Protease, the protein cleaves the polyprotein chain into individual components, which then are assembled to form the HIV virus.
