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...
