On the structure of heparitin sulfates Analyses of the products formed from heparitin sulfates by two heparitinases and a heparinase from Flavobacterium heparinum

Biochimica et Biophysica Acta (BBA) - General Subjects, 1976
The analyses of the products formed from heparitin sulfates by the action of two heparitinases and a heparinase from Flavorbacterium heparinum is reported. Heparitin sulfates A and B are degraded by heparitinase I yielding two disaccharides, one of them composed of N-acetylucosamine and an unsaturated uronic, joined by alpha(1 lead to 4) linkage, and ...

Effects of preparations of heparin and heparitin sulfate on fibrinolysis

Archives of Biochemistry and Biophysics, 1966
Abstract Some preparations of heparin and heparitin sulfate were found to be contaminated with protease inhibitors. By column chromatography two different inhibitors, both of an acid type, could be demonstrated. Inhibitor-free heparin preparations exerted an enhancing effect on fibrinolysis caused by plasminogen activators.

Interactions between mucopolysaccharides and cationic polypeptides in aqueous solution: Hyaluronic acid, heparitin sulfate, and keratan sulfate

Biopolymers, 1974
AbstractCircular dichroism spectroscopy has been used to study the interactions of hyaluronic acid, heparitin sulfate, and keratan sulfate with cationic polypeptides. The results indicate that the presence of these mucopolysaccharides has an effect in the conformation of poly(L‐lysine) and poly(L‐arginine), such that the former adopts the “random” form

The isolation and properties of heparitin sulfate from human umbilical cord tissues

Biochimica et Biophysica Acta (BBA) - General Subjects, 1970
Heparitin sulfate has been isolated from human umbilical cords in a yield of approx. 0.07% of the dry weight of tissue. Heparin was not detected, and if present, it is believed to be in considerably lower concentrations than heparitin sulfate. The isolated heparitin sulfate showed similarity to the material obtained from human aortic tissue in having ...

Reaction of heparitin sulfate with nitrous acid

Carbohydrate Research, 1968
Abstract Degradation of heparitin sulfate with nitrous acid at −20° has been shown to be a useful technique for the study of structural features of this mucopolysaccharide. Products obtained from this reaction indicate that heparitin sulfate is composed of multiple, alternating sections containing 2-acetamido-2-deoxy- O -(glycuronosyl)- d -glucose or

Chemistry of heparitin sulfate and heparin from normal tissues and from patients with hunter syndrome

Biochimica et Biophysica Acta (BBA) - General Subjects, 1979
Some structural features of heparitin sulfate excreted by patients with Hunter syndrome are described. It is shown, with the aid of heparitinases and heparinase from Flavobacterium heparinum, that the Hunter heparitin sulfate is a very complex structure composed of nine different disaccharide units containing regions akin to normal heparitin sulfate ...

The Uronidic Linkages in Heparitin Sulfate

Connective Tissue Research, 1975
Beta-glucuronidase preparations obtained from various sources were shown to liberate free D-glucuronic acid from heparitin sulfate oligosaccharides. Some free L-iduronic acid could also be detected in the hydrolyzates indicating the presence of an iduronidase in the preparations. The data presented indicate that heparitin sulfate contains a substantial
