Probing Conformational Feature of a Recombinant Pyruvate Kinase by Limited Proteolysis
Pyruvate kinase is a key enzyme in glycolytic pathway that catalyzes the transphosphorylation between phosphoenolpyruvate and ADP to yield ATP and Pyruvate. Geobacillus stearothermophillus has a stable pyruvate kinase with determined crystal structure that composed of four separate domains. Given that limited proteolysis experiments can be successfully used to probe conformational features of p...
متن کاملProbing protein structure by limited proteolysis.
Limited proteolysis experiments can be successfully used to probe conformational features of proteins. In a number of studies it has been demonstrated that the sites of limited proteolysis along the polypeptide chain of a protein are characterized by enhanced backbone flexibility, implying that proteolytic probes can pinpoint the sites of local unfolding in a protein chain. Limited proteolysis ...
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 کاملLimited proteolysis and proton n.m.r. spectroscopy of the 2-oxoglutarate dehydrogenase multienzyme complex of Escherichia coli.
The 2-oxoglutarate dehydrogenase multienzyme complex of Escherichia coli was treated with trypsin at pH 7.0 at 0 degrees C. Loss of the overall catalytic activity was accompanied by rapid cleavage of the lipoate succinyltransferase polypeptide chains, this apparent Mr falling from 50 000 to 36 000 as judged by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. A slower shortening of th...
متن کاملTopography of succinate dehydrogenase in the mitochondrial inner membrane. A study using limited proteolysis and immunoblotting.
The arrangement of the large (70,000-Mr) and small (30,000-Mr) subunits of succinate dehydrogenase in the mitochondrial inner membrane was investigated by immunoblot analysis of bovine heart mitochondria (right-side-out, outer membrane disrupted) or submitochondrial particles (inside-out) that had been subjected to surface-specific proteolysis. Both subunits were resistant to proteinase treatme...
