Facile transition of poly[d(TG).d(CA)] into a left-handed helix in physiological conditions The DNA polymer d(GC) n ·d(GC) n can undergo a transition from the usual right-handed 10.4 base pairs (bp) per turn B form to a novel left-handed 12 bp p... DB Haniford,DE Pulleyblank...
DNA can have both right-handed and left-handed double helical conformations. This idea has old roots and was considered shortly after the formulation of the double helix by Watson and Crick in 1953 (1). In this early period, attention was directed toward the question of whether or not the ...
Energetic and structural inter-relationship between DNA supercoiling and the right- to left-handed Z helix transitions in recombinant plasmids. We have evaluated the B to Z conformational transitions in supercoiled recombinant plasmids containing different lengths of (dC-dG) described in the preceding ...
In contrast to double-stranded DNA, there has so far been little evidence that double-stranded RNA can undergo major conformational transitions. We have investigated the conformation in different conditions of the double-stranded RNA molecule poly(G-C)·poly(G-C), by NMR, circular dichroism and...
Left-handed double helical DNA: variations in the backbone conformations It is now very well recognized that the DNA double helix is conformationally pluralistic and that this flexibility is derived from internal motions due to backbone torsions. But what is less apparent is that such internal motio...
The DNA fragment d(CpGpCpGpCpG) crystallises as a left-handed double helical molecule with Watson-Crick base pairs and an antiparallel organisation of the sugar phosphate chains. The helix has two nucleotides in the asymmetric unit and contains twelve base pairs per turn. It differs significantly...
Antibodies to DNA in the left-handed (Z) conformation bind to acid-fixed polytene chromosomes of both Chironomus thummi and Drosophila melanogaster, as shown by direct and indirect immunofluorescence. Comparison of the phase-contrast, immunofluorescence, and DNA staining patterns shows a predominant loca...
