The conformations of human alpha-thrombin and gamma-thrombin have been compared by circular dichroism, solvent perturbation different spectroscopy, and chemical modification. Circular dichroism studies indicate that proteolytic conversion of alpha-thrombin to gamma-thrombin is accompanied by considerable conformational changes which include a
Heparin binding and protease inhibitor activity of chemically modified antithrombin III.

Modification of tryptophanyl residues (Trps) of myosin subfragments 1 (S-1) was performed with dimethyl(2-hydroxy-5-nitrobenzyl)sulfonium bromide (DHNBS). Under controlled conditions, pH 6 at 0 degrees C and 10-min reaction with 10-100-fold molar excess, K+(EDTA) activity was reduced down to less than

Chemical modification of tryptophan residues in antithrombin III by dimethyl (2-hydroxy-5-nitrobenzyl) sulfonium bromide (HNBSB) generates products with similar levels of modification (equivalent to 0.9 mole 2-hydroxy-5-nitrobenzyl [HNB] incorporated/mole of antithrombin III) but with high or low affinity for heparin-Sepharose. Upon

Heparin has been shown to exhibit lower affinity for the antithrombin-thrombin complex than for antithrombin alone (Carlstrom, A.-S., Lieden, K., and Bjork, I. (1977) Thromb. Res. 11, 785-797), suggesting that structural alterations in antithrombin may accompany its reaction with thrombin.
