| pubmed-article:7061513 | pubmed:abstractText | Preformed Cs2SO4 zonal gradients were used to purify aggregates from proteoglycan preparations derived from associative extracts of the Swarm rat chondrosarcoma. Zonal gradients were used in solvents with different concentrations of guanidine HCl and different solvent pH values to study the mechanisms for dissociating the aggregates. Aggregates are stable in concentrations of guanidine HCl up to 1.5 M at pH 6.6. At 2 M guanidine HCl, partial dissociation occurs over 20 h in which a link protein is completely dissociated for every monomer proteoglycan dissociated from the aggregate structure. This suggests that in this solvent disaggregation occurs concurrent with complete separation of link protein from monomer. At solvent pH 2.7 to 3.3 in ionic conditions which normally promote aggregation, dissociation occurs by a mechanism in which the link protein remains associated with monomer. Thus, link protein-monomer complexes dissociate as bimolecular units from hyaluronic acid; such complexes then exhibit physical properties indistinguishable from pure monomers. The link protein-monomer complexes reassociate with hyaluronic acid to form link-stabilized aggregates when the solvent pH is raised to pH 7, i.e. to associative conditions. The study provides additional evidence for the role that link protein-monomer interactions have in proteoglycan aggregate structures. | lld:pubmed |
