'''Alpha-1-antitrypsin''' (or α1-antitrypsin, A1AT) is an inhibitor of [[Elastase]] and [[Trypsin]]. It is a member of the '''Ser'''ine '''P'''rotease '''I'''nhibitor ([[:Category:Serpin|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.
