Switching between the active (ATP and DNA bound) and inactive conformations of the homologous recombination RecA protein is regulated by ATP hydrolysis. First, we use the homologous pairing domain of RecA derived from its mobile loop L2 to show that

The disordered mobile loop L2 of the Escherichia coli RecA protein is known to play a central role in DNA binding and pairing. To investigate the local chemical environment in relation to function we performed saturation mutagenesis of the loop L2 re

We studied the formation of stable PyPuPu intermolecular triplexes under neutral pH in the presence of bivalent cations (Mg, Ca, Mn, Co, Ni, Cu, Zn, Cd, and Ba) with the help of the photo- and DMS footprinting assays. The cations which stabilize d(C)

Diethyl pyrocarbonate (DEPC) was used as a probe of local denatured regions in ccDNA pAO3 plasmid. It was found that in native ccDNA molecules only adenosine residues in the loop of the cruciform structure react with DEPC. Denaturation of ccDNA is ac

Telomeric sequences of DNA, which are found at the ends of linear chromosomes, have been attracting attention as potential sites for the formation of unusual DNA structures. They consist of (GnTm) or (GnATm) motifs (n greater than or equal to m) and,

Diethyl pyrocarbonate was used as a probe in mapping early melting stages in supercoiled DNA. It was shown that in the process of early melting of pAO3 DNA two denatured regions (about 15 b.p.) arouse near the left and right boundaries of the crucifo

We have recently shown that under superhelical stress and/or acid pH the homopurine-homopyrimidine tracts conforming to the mirror symmetry (H palindromes) form a novel DNA structure, the H form1–4. According to our model, the H form includes (1) a
