We have designed a dodecamer d-AGATCTAGATCT (RY12) with alternate oligopurines and oligopyrimidines tracts and its homologous 28 bp hairpin oligomer (RY28) that forms a triple helix only in the presence of a pentapeptide REWER. An intermolecular trip

The contribution of ATP and other nucleotides to the stabilization of non-native structures has been described for some proteins. We report here the effect of GTP, ATP, and their nonhydrolyzable analogues on the denaturation and renaturation of the e

The hairpin-duplex equilibria of the dodecamer d-AAGCTTAAGCTT and interaction of the duplex form with a pentapeptide, KGWGK, has been studied. UV thermal transitions are monophasic at low salt but biphasic at higher salt concentrations. At 10(-5) M o

The interactions of three tryptophan-containing peptides, KWK, KGWK tert-butyl ester, and KGWGK, with two self-complementary dodecamers of the same base composition but different sequence were studied by UV, CD, and fluorescence spectroscopy. The oli

We have recently reported that a GC-rich palindromic repeat sequence presumably adopts a stable fold-back tetraplex DNA structure under supercoiling. To establish the biological significance of this structure, we inserted this sequence between two di

A synthetic deoxyoligonucleotide containing five palindromic repeats of GGATCC self assembles to form a parallel four-stranded structure held together by G-tetrads that shows slower mobility than duplex DNA. This structure is hypersensitive to S1 nuc

Three specific mutants, C54I, C54W, and a double-mutant C54D:C64R of restriction endonuclease BamHI, were generated and studied to investigate the role, if any, of the 54th and 64th cysteine residues in the catalysis of BamHI. The mutation was achiev

Biochemical properties of Type II restriction enzyme Ban I were characterized. Kinetic parameters were evaluated and an enhancement of rate was observed when the recognition site was located in a more central position in the substrate, suggesting tha
