title: Affinity of protein HU for different nucleic acids.
abstract: The binding of protein HU from Escherichia coli to nucleic acids was investigated by affinity chromatography under various conditions, by a nitrocellulose retention assay and by isopycnic centrifugations in metrizamide gradients. The results indicate that HU has a preference for binding to RNA and single-stranded DNA over double-stranded DNA. The affinity of HU for supercoiled DNA was also less than that of the corresponding relaxed DNA.
