Aprotinin - from Bovine Lung
Aprotinin is a monomeric globular polypeptide derived from bovine lung tissue. It consists of a chain of 58 amino acids that fold 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.
Aprotinin inhibits several serine proteases, specifically trypsin, chymotrypsin, plasminand kallikrein. Its action on kallikrein leads to the inhibition of the formation of factor XIIa. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or < 3.Aprotinin is freely soluble in water (>10 mg/ml) as well as low ionic strength aqueous buffers.
