The promoter for the leuV tRNA operon of Escherichia coli has been studied. Derivatives of this promoter were examined in vivo, fused to the cat gene or to the lacZ gene. When compared to other promoters, the leuV promoter was found to be at least three times stronger than the tyrT promoter (for the tyrT tRNA operon), or the lac promoter (trp::lac promoter(More)
The behavior of Escherichia coli 50S ribosomal subunit proteins L7/L12 has been investigated in ribosome reconstitution buffer, TMK buffer, by sedimentation equilibrium and analytical gel filtration. Contrary to previous reports that L7/L12 exists in solution solely as dimer species [Möller, W., Groene, A., Terhorst, C., & Amons, R. (1972) Eur J. Biochem.(More)
Poly(vinylidene fluoride) (PVDF) nanocomposites are recently gaining importance due to their unique dielectric and electroactive responses. In this study, GeO2 nanoparticles/PVDF and SiO2 nanoparticles/PVDF nanocomposite films were prepared by a simple solution casting technique. The surface morphology and structural properties of the as-prepared films were(More)
