The action of the guanylyl-preferring RNase from Bacillus intermedius (binase) on a mixture of oligoadenylates with randomly distributed 2′-5′ and 3′-5′ internucleotide bonds [(A2′/3′p)n] under conditions sufficient for complete hydrolysi

A long (dG)n stretch can fold twice forming an intramolecular tetrahelix stabilized by guanine tetrads and stacking interactions between them (G-structure). In this paper, we show that magnesium ions induce a transition of the (dG)n stretch from the

Our dimethyl sulfate modification experiments suggest that (dG)n stretches within single-stranded DNA fragments, which represent the simplest model for telomeric sequences, adopt a complex intrastrand structure other than a simple hairpin. We present

Nucleotide residues in E. coli tRNA(Phe) interacting directly with proteins in pre- and posttranslocated ribosomal complexes have been identified by UV-induced cross-linking. In the tRNA(Phe) molecule located in the Ab-site (pretranslocated complex)

The action of high-intensity (10(9)-10(12) W/m2) UV (266 nm) laser radiation pulses (duration ca 10 ns or ca 40 ps) on liquid aqueous solutions of DNA is known to cause not only single- but also two-quantum modification of nucleic bases. The action o

Plasmids containing (dG)27.(dC)27 inserts (pPG27), (dG)37.(dC)37 inserts (pPG37), and (dG)24C(dG)21.(dC)24G(dC)21 inserts (pPG46C) were constructed for the study of structural transitions within (dG)n.(dC)n stretches. Two-dimensional gel electrophore

The reproduction of phage T7 in the presence of hydroxylamine (HA) (mutagenesis in vivo) results in the phenotypic suppression of some amber mutants. The presence of O-methyldroxylamine (OMHA) results in a similar effect, indcating a similar mechanis

Monomercurated tRNA has been prepared by exhaustive treatment of mercaptoethanol on polymercurated tRNA under non-denaturing conditions. The remained mercury atom is stable toward ultraviolet (254 nm) irradiation up to absorption of 100 quanta/nucleo

Ultraviolet irradiation (254 nm) of the complexes of MS2 phage RNA (mRNA) and the 30-S subunits of Escherichia coli ribosomes prepared at 0 degrees C and 37 degrees C in the presence and absence of initiation factor 3 (IF-3) causes cross-linking of m
