Octasaccharide 3-17 serpin family C member 1 Homo sapiens 100-112 3427019-2 1987 The octasaccharide produced a maximum 48% increase in intrinsic fluorescence at 37 degrees C and a rate of factor Xa inhibition of 6 X 10(5) M-1 s-1 as measured by stopped-flow fluorometry at 25 degrees C. The basal rate of the antithrombin-factor Xa interaction observed in the absence of oligosaccharide was 2 X 10(3) M-1 s-1. Octasaccharide 4-18 serpin family C member 1 Homo sapiens 228-240 2732232-10 1989 A size dependence was observed for the heparin effect since an anticoagulantly active octasaccharide fragment of heparin, with avid antithrombin binding activity, was without effect on the inactivation of antithrombin by neutrophil elastase. Octasaccharide 86-100 serpin family C member 1 Homo sapiens 132-144 6530392-2 1984 A marked difference in the inhibitory activity for thrombin in the presence of antithrombin III was observed between the high-affinity fractions for antithrombin III of octasaccharide approximately hexadecasaccharide and those of octadecasaccharide approximately eicosasaccharide. Octasaccharide 169-183 serpin family C member 1 Homo sapiens 79-95 6525337-1 1984 We have isolated from nitrous acid cleavage products of heparin two major octasaccharide fragments which bind with high affinity to human antithrombin. Octasaccharide 74-88 serpin family C member 1 Homo sapiens 138-150 6525337-4 1984 This suggests that the conformation of antithrombin in the region of the factor Xa binding site is similar when the protease inhibitor is complexed with either octasaccharide. Octasaccharide 160-174 serpin family C member 1 Homo sapiens 39-51 6698980-14 1984 A model of the antithrombin III-binding octasaccharide (Lindahl, U., Backstrom, G., Thunberg, L., and Leder, I. G. (1980) Proc. Octasaccharide 40-54 serpin family C member 1 Homo sapiens 15-31 6698980-19 1984 These two models can be positioned such that the three lysine residues in the alpha-helix can be matched for maximal interaction with the three sulfate groups in the octasaccharide demonstrated as essential for binding antithrombin III. Octasaccharide 166-180 serpin family C member 1 Homo sapiens 219-235 6583694-1 1984 We have examined the quantitative importance of various monosaccharide residues of an octasaccharide domain of heparin that are responsible for the binding of this oligosaccharide to antithrombin. Octasaccharide 86-100 serpin family C member 1 Homo sapiens 183-195 6583694-2 1984 Different fragments of the octasaccharide were prepared by enzymatic digestion and the avidities of these oligosaccharides for antithrombin were determined by equilibrium dialysis. Octasaccharide 27-41 serpin family C member 1 Homo sapiens 127-139 6486808-3 1984 Preincubation of antithrombin with the octasaccharide binding domain of heparin prior to treatment with dimethyl-(2-hydroxy-5-nitrobenzyl) sulfonium bromide was able to suppress modification of the critical tryptophan and preserve the functional capacities of the protease inhibitor. Octasaccharide 39-53 serpin family C member 1 Homo sapiens 17-29 6530392-2 1984 A marked difference in the inhibitory activity for thrombin in the presence of antithrombin III was observed between the high-affinity fractions for antithrombin III of octasaccharide approximately hexadecasaccharide and those of octadecasaccharide approximately eicosasaccharide. Octasaccharide 169-183 serpin family C member 1 Homo sapiens 149-165 6885772-2 1983 An octasaccharide with high affinity for antithrombin, isolated after partial deaminative cleavage of heparin, was previously found to have an L-iduronosyl-N-acetylglucosaminyl-6-O-sulfate nonreducing terminal disaccharide unit. Octasaccharide 3-17 serpin family C member 1 Homo sapiens 41-53 6885772-3 1983 After digestion of this octasaccharide with alpha-L-iduronidase and N-acetylglucosamine-6-sulfate sulfatase, two fractions, with high and low affinity for antithrombin, respectively, were isolated by affinity chromatography on antithrombin-Sepharose. Octasaccharide 24-38 serpin family C member 1 Homo sapiens 155-167 6935668-1 1980 An octasaccharide with high affinity for antithrombin was isolated after partial deaminative cleavage of heparin with nitrous acid. Octasaccharide 3-17 serpin family C member 1 Homo sapiens 41-53 7083257-1 1982 An octasaccharide with high affinity for antithrombin, isolated after partial deaminative cleavage of heparin and previously found to have the following predominant structure (see formula in text) has been studied further. Octasaccharide 3-17 serpin family C member 1 Homo sapiens 41-53 7083257-11 1982 It is concluded that the antithrombin binding site in heparin is represented by the pentasaccharide sequence extending from unit 2 to unit 6 of the octasaccharide studied. Octasaccharide 148-162 serpin family C member 1 Homo sapiens 25-37 7338523-1 1981 Porcine intestinal heparin was partially digested with a purified heparinase and an octasaccharide with high-affinity for antithrombin III was isolated from the digest by gel filtration, followed by affinity chromatography on a column of Sepharose 4B coupled with antithrombin III. Octasaccharide 84-98 serpin family C member 1 Homo sapiens 122-138 7338523-1 1981 Porcine intestinal heparin was partially digested with a purified heparinase and an octasaccharide with high-affinity for antithrombin III was isolated from the digest by gel filtration, followed by affinity chromatography on a column of Sepharose 4B coupled with antithrombin III. Octasaccharide 84-98 serpin family C member 1 Homo sapiens 264-280 7338523-3 1981 Fifty percent inactivation activities of the octasaccharide for thrombin and factor Xa in the presence of antithrombin III were 2 and 6.5 times, respectively, higher than those of the initial heparin. Octasaccharide 45-59 serpin family C member 1 Homo sapiens 106-122 28340300-7 2017 We identified a novel octasaccharide that interacts with antithrombin and displays anti factor Xa activity.

Octasaccharide 34-48 serpin family C member 1 Homo sapiens 49-61 23083208-5 2013 The presence of the second 3-O-sulfated glucosamine in the octasaccharide induced more than one order of magnitude increase in affinity to antithrombin compared to the pentasaccharide AGA*IA.
