Oligosaccharides 310-325 serpin family C member 1 Homo sapiens 136-148 8357789-5 1993 We found (i) that binding to antithrombin of all these oligosaccharides resulted in transmission of conformational change to P1 in the reactive center, (ii) that these oligosaccharides all gave enhancements of the rate of inhibition of factor Xa beyond any contribution from surface approximation, and (iii) that the degree of perturbation of P1 correlated with the enhancement of the rate of factor Xa inhibition that was not due to surface approximation. Oligosaccharides 55-71 serpin family C member 1 Homo sapiens 29-41 8357789-5 1993 We found (i) that binding to antithrombin of all these oligosaccharides resulted in transmission of conformational change to P1 in the reactive center, (ii) that these oligosaccharides all gave enhancements of the rate of inhibition of factor Xa beyond any contribution from surface approximation, and (iii) that the degree of perturbation of P1 correlated with the enhancement of the rate of factor Xa inhibition that was not due to surface approximation.
