DNA with adenine tracts contains poly(dA).poly(dT) conformational features in solution.

The conformation of DNA's with adenine-thymine tracts exhibiting retardation in electrophoretic migration and considered as curved were investigated in solution by CD and RAMAN spectroscopy. The following curved multimers with adenine tracts but of different flanking sequences d(CA5TGCC)n, d(TCTCTA6TATATA5)n, d(GA4T4C)n yield CD spectroscopic features indicating a non-B structure of the dA.dT t...

Polyamines preferentially interact with bent adenine tracts in double-stranded DNA

Polyamines, such as putrescine, spermidine and spermine, have indirectly been linked with the regulation of gene expression, and their concentrations are typically increased in cancer cells. Although effects on transcription factor binding to cognate DNA targets have been demonstrated, the mechanisms of the biological action of polyamines is poorly understood. Employing uranyl photo-probing we ...

Conformational properties of DNA strands containing guanine-adenine and thymine-adenine repeats.

CD spectroscopy and PAGE were used to cooperatively analyze melting conformers of DNA strands containing GA and TA dinucleotide repeats. The 20mer (GA)10 formed a homoduplex in neutral solutions containing physiological concentrations of salts and this homoduplex was not destabilized even in the terminal (GA)3 hexamers of (GA)3(TA)4(GA)3, although the central (TA)4 portion of this oligonucleoti...

X-ray conformational study of the DNA duplex in solution.

Earlier x-ray studies on dissolved linear DNA molecules were interpreted on the assumption that the molecules scattered as rigid rods. Improvement in equipment and advances in theory of the scattering from randomly oriented helices prompted us into a reinvestigation of this problem. Careful measurements were made on the scattering from both linear calf thymus DNA and from circular plasmid COP60...

DNA conformational analysis in solution by uranyl mediated photocleavage

Uranyl mediated photocleavage of double stranded DNA is proposed as a general probing for DNA helix conformation in terms of minor groove width/electronegative potential. Specifically, it is found that A/T-tracts known to constitute strong distamycin binding sites are preferentially photocleaved by uranyl in a way indicating strongest uranyl binding at the center of the minor groove of the AT-r...
