title: Aminoglycoside antibiotics: inactivation by phosphorylation in Escherichia coli carrying R factors.
abstract: R-factor strains which are streptomycin-resistant and spectinomycin-sensitive have been found to inactivate streptomycin by a new mechanism. The 3'-OH group of the 2-deoxy-2-methylamino-l-glucopyranosyl moiety is phosphorylated.
