Implication

Electrophoretic analysis reveals sequence-dependent kinks at dinucleotide steps in curved DNA, suggesting a novel mechanism for structural protein-DNA recognition.

Key Points

To investigate the structural basis of length-dependent gel retardation anomalies in curved DNA fragments devoid of AA dinucleotides.
Assessed electrophoretic mobility and gel retardation behavior across varied fragment lengths of curved DNA lacking AA dinucleotides.
Evaluated electric-field and length-dependent structural transitions occurring specifically at CA/TG and TA/TA base steps.
Gel retardation anomalies in curved fragments reached a maximum as fragment length increased, indicating electric-field and length-dependent structural transitions.
Thermally induced stereochemical kinks were stabilized within the gel matrix specifically at CA/TG and TA/TA dinucleotide steps, relieving DNA curvature effects.
