One of the characteristic manifestations of biological activity of proteins resides in their ability to elicit antibody formation. While the activity of certain immune bodies, as well as that of enzymes, or viruses, is known to be destroyed by processes causing protein denaturation, the relation between denaturation and antigenicity is only vaguely understood. I t has been reported that denatur...

 Immobilization of Lipase produced from Rhizomucor miehei on HDPE fine powder was investigated. As compared to an aqueous system, immobilization in a non-aquous organic medium such as n-hexane was not successful and caused enzyme denaturation. Prewetting the support with ethanol increased the immobilized protein and enzyme activity as much as 31% and 34%, respectively. The maximum immobilized a...

Crystalline soybean trypsin inhibitor protein undergoes denaturation on heating which is reversed on cooling. In the range of temperature of 35 to 50 degrees C. a solution of the protein consists of a mixture of native and denatured forms in equilibrium with each other. The equilibrium is only slowly established and its final value at any temperature is the same whether a heated, denatured solu...

Bile Pigments, Protein Interaction, Conformation, Denaturation The chromophore-protein interactions of C-phycocyanin (C-PC) from Spirulina platensis have been studied by following the partial and complete denaturation with UV-Vis spectroscopy. From comparison with published MO calculations, an elongated conformation of the chromophore is sug­ gested for native C-PC, a cyclic one for denatured C...
