Millimolar concentrations of divalent cations are shown to affect the size of toroids formed when DNA is condensed by multivalent cations. The origins of this effect were explored by varying the order in which MgCl(2) was added to a series

In this study, a new small-molecule-based reagent was designed to recognize and bind to specific site in protein. A new pyrenyl probe, d-biotinyl-1(1-pyrene)methylamide (Py-biotin) was designed and synthesized by coupling of d-biotin to 1(1-pyrene)methylamine hydrochloride. Binding studies and site-specific photocleavage

The Holliday junction is a central intermediate in genetic recombination. This four-stranded DNA structure is capable of spontaneous branch migration, and is lost during standard DNA extraction protocols. In order to isolate and characterize recombination intermediates that contain Holliday junctions

The RecG protein of Escherichia coli is a junction-specific DNA helicase that drives branch migration of Holliday intermediates in genetic recombination and DNA repair. The reaction was investigated using synthetic X-junctions. RecG dissociates X-junctions to flayed duplex products, although DNA
