We have designed novel macromolecular coordination ligands (MCLs) by conjugation of thermoresponsive polymers based on poly(N-isopropylacrylamide) (M ̅_n around 3 to 25 kg∙mol-1) with 1,2,4-triazole coordination sites. These triazole units...

Gel Transition

Water-soluble, partially cross-linked poly-2-isopropyl-2-oxazoline combining the properties of chemical and physical gels was synthesized by a two-step procedure. Thermally induced sol-gel transition in its aqueous solution was studied by rheology, light scattering, and turbidimetry. It was demonstrated that the synthesized product is bimodal; it consists of linear and cross-linked components. The cross-linked components are responsible for the gelation, while the linear ones abate the viscosity growth. Heating the solution above the phase transition temperature leads to the self-assembly of the particles into a physical gel. The combination of chemical and physical cross-linking was found to be a prospective route for thermosensitive gel development.

Sequence Similarities

Human haptoglobin (Hp) has been shown to have chaperone-like activity in preventing thermally induced aggregation of catalase and γ-crystallin. No differences in the chaperone- like behaviour of genetic types Hp 1-1 and a mixture of types Hp 2-1 and Hp 2-2 (i.e. Hp II) were found. Haptoglobin not only suppresses heat-induced aggregation of proteins but also prevents γ-crystallin from aggregation by oxidative stress. In addition, haptoglobin also provides protection against glycation-induced inactivation of catalase by glyceraldehyde. Chaperone-like activity of haptoglobin decreases in the course of its glycation. Refolding studies have shown that Hp exhibits its chaperone-like activity predominantly on the unfolding and not on the refolding pathway. Although Hp and α-crystallin have no sequence similarities, it seems that their chaperone-like activities are of the same type.
