We have expressed recombinant RNase P protein from Escherichia coli in high yield. A hexahistidine sequence at the amino terminus allowed protein purification in a single step. Mass spectrometry confirmed the molecular weight of the purified protein and indicated a purity of > 95%. Protein functionality was demonstrated by reconstitution of active holoenzyme.

Site-specific fluorescent labeling of proteins in vivo remains one of the most powerful techniques for imaging complex processes in live cells. Although fluorescent proteins in many colors are useful tools for tracking expression and localization of fusion proteins in cells, these relatively large tags (>220 aa) can perturb protein folding, trafficking and function. Much smaller genetically enc...

BACKGROUND Making peptide pharmaceuticals involves challenging processes where many barriers, which include production and manufacture, need to be overcome. A non common but interesting research area is related to peptides with intracellular targets, which opens up new possibilities, allowing the modulation of processes occurring within the cell or interference with signaling pathways. However,...

Recombinant clathrin protein fragments form assemblies that template gold nanocrystals in an array across the latticed surface. The nanocrystals exhibit unusual anisotropic morphologies with long range ordering, both of which are dependent upon the presence of a hexahistidine tag on the clathrin heavy chain fragments.

BOURDIEU’S CONSTRUCT OF HABITUS AND CRITIQUE The current sociological understanding of habitus expressed in the work of Pierre Bourdieu as its key academic construct emphasizes the importance of habits for human action. Bourdieu understands human behavior as fundamentally cultural; rejecting behaviorist view of cognition and action as related to a stimulus—response chains, the French sociologis...

In fact, a given agent’s practical relation to the future, which governs his present practice, is defined in the relationship between, on the one hand, his habitus with its temporal structures and dispositions towards the future, constituted in the course of a particular relationship to a particular universe of probabilities, and on the other hand a certain state of the chances objectively offe...
