Hoogsteen base pairs proximal and distal to echinomycin binding sites on DNA.
Forms of the DNA double helix containing non-Watson-Crick base-pairing have been discovered recently based on x-ray diffraction analysis of quinoxaline antibiotic-oligonucleotide complexes. In an effort to find evidence for Hoogsteen base-pairing at quinoxaline-binding sites in solution, chemical "footprinting" (differential cleavage reactivity) of echinomycin bound to DNA restriction fragments...
متن کاملDifferential ability of proximal and remote element pairs to cooperate in activating RNA polymerase II transcription.
To investigate the synergism or cooperative interaction between transcription elements, we have designed and constructed a series of synthetic polymerase II promoters with different combinations of elements. These include three different CCAAT boxes, which correspond to the binding sites for CP1, CP2, and NFI, a GC box, a CACCC box, and an ATF/CREB-binding site. The synthetic promoters containi...
متن کاملChronic Proximal Biceps Tendinitis in Young Patients with Anatomic Proximal Origin Variations: A case series
Purpose: To describe a case series of young adult patients with isolated chronic proximal biceps tendinitis refractory to conservative care found to have anatomic long head biceps tendon (LHBT) origin variations who underwent arthroscopic-assisted subpectoral biceps tenodesis. Methods: Patients were included in this retrospective case series if they met all the following criteria: 1) had ...
متن کاملON RELATIVE CENTRAL EXTENSIONS AND COVERING PAIRS
Let (G;N) be a pair of groups. In this article, first we con-struct a relative central extension for the pair (G;N) such that specialtypes of covering pair of (G;N) are homomorphic image of it. Second, weshow that every perfect pair admits at least one covering pair. Finally,among extending some properties of perfect groups to perfect pairs, wecharacterize covering pairs of a perfect pair (G;N)...
متن کاملCotorsion Pairs Induced by Duality Pairs
We introduce the notion of a duality pair and demonstrate how the left half of such a pair is “often” covering and preenveloping. As an application, we generalize a result by Enochs et al. on Auslander and Bass classes, and we prove that the class of Gorenstein injective modules—introduced by Enochs and Jenda—is covering when the ground ring has a dualizing complex.
