Paromomycin and dihydrostreptomycin binding to Escherichia coli ribosomes.

Paromomycin binds specifically to a single type of binding site on the 70-S streptomycin-sensitive Escherichia coli ribosome. This site is different from that of dihydrostreptomycin since paromomycin binds to streptomycin-resistant ribosomes and sine dihydrostreptomycin does not compete for paromomycin binding. Paromomycin binding, unlike… (More)
