[…] (selex), we demonstrated the first aptamer (s15) that can bind to denv-2 envelop protein domain iii (ed3) with a high binding affinity. s15 was found to form a parallel quadruplex based on quadfinder prediction, gel mobility assay and circular dichroism studies. both the quadruplex structure and the sequence on 5’-end were necessary for the binding activity of s15. nmr titration […]

[…] (). the resulting amplicons were purified and sequenced as above., predictions of putative g4 motifs were made using the software algorithms quadparser g4p_calculator.exe , qgrs mapper , quadfinder , qgrs predictor . where necessary, both strands were analysed separately to ensure g4-motifs were detected in both orientations. primer design, analysis of sequence alignments, and dna […]

[…] the c-myc gene., to determine how widespread the phenomenon of 5hmc incorporation into putative im structures in genomic dna is, we first identified all of the putative unimolecular ims using the quadfinder tool developed by scaria et al. this tool searches for sequences composed of cxnycxnycxnycx motifs (for ims on template strands) or gxnygxnygxnygx motifs (for ims on nontemplate strands), […]

[…] structures did not account for g-quadruplex formation, which was considered as a possible secondary structure given observations of the sequences’ high g-content, particularly for ag3 (see ). a quadfinder analysis showed potential for g-quadruplexes mostly in regions shared by the random region and the primer region (data not shown). indeed, a dna melt experiment at 295 nm shows an initial […]

[…] when qs are present in the 5′ untranslated region of the mrna, it can interfere with ribosome binding and translation initiation (,)., when we analyzed the whole c. difficile (strain 630) genome in quadfinder, an online server for prediction of quadruplex-forming motifs in nucleotide sequences (), we found five pqs. unfortunately, none of these were located in the paloc, where tcdc […]
