摘要:
A method for solubulizing and refolding insoluble aggregates of HCV protease is presented. Insoluble aggregates of HCV NS3 protease are extracted from bacteria producing the aggregates. The aggregates of HCV NS3 are then solubilized in a buffer containing the denaturing reagent. Solubilized protease is then placed in an acidic buffer containing a reducing agent. The denaturing reagent is then removed from the buffer under acidic conditions. The pH of the buffer containing HCV NS3 protease is then raised in a step-wise manner to a pH of about 7-8 so as to produce properly refolded soluble, active HCV NS3 protease.

The present invention discloses nucleic acids that encode an active human Aurora 2 kinase catalytic domain. The present invention also discloses methods of growing X-ray diffractable crystals of polypeptides comprising the active human Aurora 2 kinase catalytic domain. The present invention further discloses a crystalline form of a catalytic domain of human Aurora 2 kinase. In addition, the present invention discloses methods of using the X-ray diffractable crystals of human Aurora 2 kinase in structure assisted drug design to identify compounds that can modulate the enzymatic activity of human Aurora 2 kinase.
摘要:
Novel synthetic polypeptides comprising the amino acid subsequence Arg-Arg-Lys-Trp-Gln are provided by this invention. Also provided are methods for the use of such polypeptides, other known polypeptides containing such subsequence and a variety of acidic or basic polypeptides and proteins as inhibitors of the binding of gamma interferon to its cellular receptors. The methods of this invention are potentially applicable to the treatment of pathological conditions believed to be mediated by gamma interferon, such as autoimmune disease.
