Absence of large-scale conformational change upon limited proteolysis of ovalbumin, the prototypic serpin.
1H and 31P NMR spectroscopies have been used to examine the effects of limited proteolysis with subtilisin Carlsberg on the global conformation of ovalbumin and on the local environment of phosphoserine 344, a residue two positions removed from the site of proteolysis. Such limited proteolysis has been shown to result in excision of a hexapeptide from the region of the protein that, in other se...
متن کاملProbing 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 کاملSampling small-scale and large-scale conformational changes in proteins and molecular complexes.
Sampling of small-scale and large-scale motions is important in various computational tasks, such as protein-protein docking and ligand binding. Here, we report further development and applications of the activation-relaxation technique for internal coordinate space trajectories (ARTIST). This method generates conformational moves of any complexity and size by identifying and crossing well-defi...
متن کاملLimited in vivo proteolysis of aggregated proteins.
Degradation pathways of insoluble proteins have been analyzed in Escherichia coli by using a N-terminal beta-galactosidase fusion protein (VP1LAC) that aggregates immediately after its synthesis. In recombinant E. coli cells, lower molecular mass products, antigenically related to the entire fusion, accumulate together with the entire fusion. In absence of protein synthesis, the insoluble intac...
متن کاملpFlexAna: detecting conformational changes in remotely related proteins
The pFlexAna (protein flexibility analyzer) web server detects and displays conformational changes in remotely related proteins, without relying on sequence homology. To do so, it first applies a reliable statistical test to align core protein fragments that are structurally similar and then clusters these aligned fragment pairs into 'super-alignments', according to the similarity of geometric ...
