'Enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli (EPEC) organisms are groups of pathogenic strains whose infections are characterized by a typical lesion of enterocyte attachment and effacement. They are involved in enteric diseases both in humans and in animals, and EHEC strains can be responsible for hemolytic uremic syndrome ... More

The DNA cleavage properties of metallobleomycins conjugated to three solid supports were investigated using plasmid DNA, relaxed covalently closed circular DNA, and linear duplex DNA as substrates. Cleavage of pBR322 and pSP64 plasmid DNAs by Fe(II).BLM A(5)-CPG-C(2) was observed with efficiencies not dissimilar to that obtained using free Fe(II).BLM A(5). ... More
