DNA supercoiling changes the spacing requirement of two lac operators for DNA loop formation with lac repressor.

We have used a gel retardation assay to investigate the influence of DNA supercoiling on loop formation between lac repressor and two lac operators. A series of 15 DNA minicircles of identical size (452 bp) was constructed carrying two lac operators at distances ranging from 153 to 168 bp. Low posit...
