Daunomycin modifies the sequence-selective recognition of DNA by actinomycin.

The antitumour antibiotic actinomycin D normally binds to DNA by intercalation at sequences containing the CpG step, but in the presence of daunomycin it has been reported to interact with poly(dA-dT). This observation has neither been confirmed nor explained. Here we have used a photoreactive 7-azido derivative of actinomycin to study the effect of daunomycin on its binding to three DNA fragme...

A MODEL FOR THE BASIC HELIX- LOOPHELIX MOTIF AND ITS SEQUENCE SPECIFIC RECOGNITION OF DNA

A three dimensional model of the basic Helix-Loop-Helix motif and its sequence specific recognition of DNA is described. The basic-helix I is modeled as a continuous ?-helix because no ?-helix breaking residue is found between the basic region and the first helix. When the basic region of the two peptide monomers are aligned in the successive major groove of the cognate DNA, the hydrophobi...

A resonance light scattering quenching system for studying DNA sequence recognition of actinomycin D.

The DNA sequence recognition study of DNA-targeted anticancer drugs is a theoretical basis for improving the selectivity of anticancer drugs. With the high synergy effect of cocoamidopropyl hydroxy sulfobetaine (HSB), a resonance light scattering (RLS) quenching system for DNA sequence recognition studies of actinomycin D (ACTD) was developed in this contribution. By the strategy, DNA sequence ...
