Alteration of Ribosomal Protein S4 by Mutation Linked to Kasugamycin-Resistance in Escherichia coli

RESUMO

An alteration in the chromatographic mobility of 30S ribosomal protein S4 from two kasugamycin-resistant (ksgA) strains of E. coli was observed. The locus determining this alteration frequently cotransduced with ksgA but could be separated from it by transduction and conjugation. Since the structural gene for protein S4 is thought to lie some 30 min from ksgA on the E. coli chromosome, the product of the newly-identified gene may modify protein S4. We propose to designate this gene ramB.
