Structural Organization of Mammalian Prions as Probed by Limited Proteolysis
Elucidation of the structure of PrP(Sc) continues to be one major challenge in prion research. The mechanism of propagation of these infectious agents will not be understood until their structure is solved. Given that high resolution techniques such as NMR or X-ray crystallography cannot be used, a number of lower resolution analytical approaches have been attempted. Thus, limited proteolysis h...
متن کاملStructural determinants of limited proteolysis.
Limited or regulatory proteolysis plays a critical role in many important biological pathways like blood coagulation, cell proliferation, and apoptosis. A better understanding of mechanisms that control this process is required for discovering new proteolytic events and for developing inhibitors with potential therapeutic value. Two features that determine the susceptibility of peptide bonds to...
متن کاملStructural characterization of the molten globule state of apomyoglobin by limited proteolysis and HPLC-mass spectrometry.
A method to characterize the structural conformation of an acidic molten globule apomyoglobin (apoMb) at pH 4.2 was developed using limited proteolysis and HPLC-mass spectrometry (HPLC-MS). Endoproteinase Glu-C, which has a double maximum activity at pH 4.0 and pH 7.8 toward glutamic acid (Glu), was used as a proteolytic enzyme. Using this method enabled us to compare the proteolytic cleavages ...
متن کاملFunctional characterization of the Tn5 transposase by limited proteolysis.
The 476 amino acid Tn5 transposase catalyzes DNA cutting and joining reactions that cleave the Tn5 transposon from donor DNA and integrate it into a target site. Protein-DNA and protein-protein interactions are important for this tranposition process. A truncated transposase variant, the inhibitor, decreases transposition rates via the formation of nonproductive complexes with transposase. Here...
متن کاملStructural studies on a mitochondrial glyoxalase II.
Glyoxalase 2 is a beta-lactamase fold-containing enzyme that appears to be involved with cellular chemical detoxification. Although the cytoplasmic isozyme has been characterized from several organisms, essentially nothing is known about the mitochondrial proteins. As a first step in understanding the structure and function of mitochondrial glyoxalase 2 enzymes, a mitochondrial isozyme (GLX2-5)...
