Alpha-1 antitrypsin (AAT) is an antiprotease, produced mainly by hepatocytes, that opposes the activity of human neutrophil elastase and several other proteases, including proteinase-3 and plasmin activator. Its normal plasma concentration is in the range of 120–200 mg/dL. 1, 2. navy webmail owa eastThis is a family of protease suicide inhibitors called the serpins. It contains inhibitors of multiple cysteine and serine protease families. Their mechanism of action relies on undergoing a large conformational change which inactivates their target's catalytic triad. Proteinase propeptide inhibitors (sometimes referred to as activation peptides) are responsible for the modulation of folding and activity of the peptidase pro-enzyme or zymogen.
