Stability of Hirudin, a Thrombin-specific Inhibitor
Hirudin is a 65-amino acid polypeptide with three disulfide linkages. It is stable under extreme pH (1.4712.9), high temperature (95 “C), and in the presence of denaturants (6 M guanidinium chloride or 8 M urea). The thrombin inhibitory activity of hirudin remains unaffected even after cleavage of an internal peptide bond ( L y ~ ~ ‘ A s n ~ ~ ) . One condition which effectively and irreversibl...
متن کاملThe direct thrombin inhibitor hirudin.
This review discusses the pharmacology and clinical applications of hirudin, a bivalent direct thrombin inhibitor (DTI). Besides the current major indication for hirudin--anticoagulation of patients with heparin-induced thrombocytopenia (HIT)--the experience with hirudin in other indications, especially acute coronary syndromes, are briefly presented. Hirudins have been formally studied prior t...
متن کاملElafin: an elastase-specific inhibitor of human skin. Purification, characterization, and complete amino acid sequence.
A potent inhibitor of human leukocyte elastase (EC 3.4.21.37) and porcine pancreatic elastase (EC 3.4.21.36) was purified to homogeneity from human horny layers. It inhibits human leukocyte elastase and porcine pancreatic elastase in a 1:1 molar ratio and shows equilibrium dissociation constants of 6 x 10(-10) M and 1 x 10(-9) M, respectively. Inhibition of plasmin, trypsin, alpha-chymotrypsin,...
متن کاملThe Complete Amino Acid Sequence of Papain
The active cysteine of papain was labeled with W-iodoacetate and the cystine residues were reduced and coupled with unlabeled iodoacetate. The heptacarboxymethyl papain was then maleylated and hydrolyzed with trypsin. Key peptides were isolated from this hydrolysate which have permitted completion of the amino acid sequence of the protein. Thus, an earlier tentative and incomplete version of th...
