Effect of methylmercuric chloride (MMC) on fibrin polymerization. 1993

Methylmercuric chloride (MMC) in concentrations 0.1-10 microM reduces the amount of fibrinopeptides released from thrombin-activated human fibrinogen. However, the fibrin clot formation is not discriminated and the turbidity of the fibrin gel is even augmented. MMC does not cause such changes in the process of repolymerization of fibrin monomers. The addition of fibrinopeptides to the fibrin monomers results in a similar increase of turbidity of the repolymerizing sample in the presence of MMC as in the case of fibrinogen clotting. These experiments indicate that MMC modifies the structure of fibrin in the presence of fibrinopeptides.

D005340 Fibrinogen Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
