Chromatographic analysis of antituberculosis drugs in biological samples.

Numerous chromatographic and non-chromatographic methods of analysis for anti-tuberculosis drugs and metabolites in biological tissues have been discussed in this review. Depending upon the analytical methodology selected, limits of detection range from microgram to picogram levels. A number of examples have been given of the correlation between different types of assay procedures. The metabolism and pharmacokinetics have been described along with some of the commonly associated problems of sample collection and storage.

Hydrolysis of GTP by elongation factor G drives tRNA movement on the ribosome.

Elongation factor G (EF-G) is a GTPase that is involved in the translocation of bacterial ribosomes along messenger RNA during protein biosynthesis. In contrast to current models, EF-G-dependent GTP hydrolysis is shown to precede, and greatly accelerate, the rearrangement of the ribosome that leads to translocation. Domain IV of the EF-G structure is crucial for both rapid translocation and subsequent release of the factor from the ribosome. By coupling the free energy of GTP hydrolysis to translocation, EF-G serves as a motor protein to drive the directional movement of transfer and messenger RNAs on the ribosome.
