Alpha-1 antitrypsin or α 1-antitrypsin (A1AT, α 1 AT, A1A, or AAT) is a protein belonging to the serpin superfamily. It is encoded in humans by the SERPINA1 gene . A protease inhibitor , it is also known as alpha 1 –proteinase inhibitor ( A1PI ) or alpha 1 -antiproteinase ( A1AP ) because it inhibits various proteases (not just trypsin ). [ 5 ]
Alpha-1 antitrypsin deficiency (A1AD or AATD) is a genetic disorder that may result in lung disease or liver disease. [1] Onset of lung problems is typically between 20 and 50 years of age. [ 1 ] This may result in shortness of breath , wheezing , or an increased risk of lung infections .
Aprotinin is a monomeric (single-chain) globular polypeptide derived from bovine lung tissue. It has a molecular weight of 6512 Da and consists of 16 different amino acid types arranged in a chain 58 residues long [4] [5] that folds into a stable, compact tertiary structure of the 'small SS-rich" type, containing 3 disulfides, a twisted β-hairpin and a C-terminal α-helix.
The identification of the S and Z mutations [21] [22] responsible for the genetic deficiency and the subsequent sequence alignments of alpha1-antitrypsin and antithrombin in 1982 led to the recognition of the close homologies of the active sites of the two proteins, [23] [24] centred on a methionine [25] in alpha1-antitrypsin as an inhibitor of ...
Trypsin is an enzyme in the first section of the small intestine that starts the digestion of protein molecules by cutting long chains of amino acids into smaller pieces. It is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyzes proteins.
Alpha 2-antiplasmin (or α 2-antiplasmin or plasmin inhibitor) is a serine protease inhibitor (serpin) responsible for inactivating plasmin. [5] Plasmin is an important enzyme that participates in fibrinolysis and degradation of various other proteins.
