Alpha-1-antitrypsin (or α1-antitrypsin, A1AT) is an inhibitor of Trypsin. It is a member of the Serine Protease Inhibitor (Serpin) family, and as such undergoes a conformational change where a loop region becomes ordered as a Beta Strand. In this case Trypsin is inhibited when a covalent bond is formed to A1AT. With A1AT, as with most members of the Serpin family, the transition from inactive precursor protein to active complex comes after a cleavage event. Shown is a morph, generated by the Yale Morph Server that shows A1AT going from its inactive form, to the conformation in which it is bound to Trypsin (also shown in the same animation).
