Bacterial elongation factor P (EF-P) plays a pivotal role in the translation of polyproline motifs. To stimulate peptide bond formation, EF-P must enter the ribosome via an empty E-site. Using fluorescence-based single-molecule tracking, Mohapatra et al. (S. Mohapatra, H. Choi, X. Ge, S. Sanyal, and J. C. Weisshaar, mBio 8:e00300-17, 2017, https://doi.org/10.1128/mBio.00300-17) monitored the ce...

background: elongation factor-1, a conserved nuclear protein coding gene was used to identify iranian sandfly species. the phlebotomine sandfies are the vectors of the parasitic protozoan leishmania, the causative agents of leishmaniasis, in iran. methods: seven sets of primers were tried. pcr amplification of elongation factor-1 was successfully achieved for all 14 species of iranian sandfli...

A new species of the genus Tychobythinus Ganglbauer, 1896, Tychobythinusoculatus sp. n., is described from near Köyceğiz, Muğla Province, in southwestern Turkey. The new species is morphologically closely related to Tychobythinusabnormipes Reitter, 1910, and Tychobythinuspauper Kiesenwetter, 1858, but can be readily distinguished from both by having very simplified internal armature of the aede...

Let Uq(sl2) be the quantized enveloping algebra associated to the simple Lie algebra sl2. In this paper, we study the quantum double Dq of the Borel subalgebra Uq((sl2) ) of Uq(sl2). We construct an analogue of Kostant–Lusztig Z[v, v]-form for Dq and show that it is a Hopf subalgebra. We prove that, over an algebraically closed field, every simple Dq-module is the pullback of a simple Uq(sl2)-m...
