✦ Synopsis

Strains carrying both the ramA1 and the neaA301 mutations do not exhibit the restriction of informational suppressors normally associated with resistance to neamine. Furthermore, ribosomes from such strains exhibit increased misreading in vitro with respect to particles from the neaA strain. These properties suggest that translational fidelity may be cooperatively controlled by ribosomal proteins S4 and S17, coded by ramA (rpsd) and neaA (rpsq) genes respectively.

A class of rpoB mutations is described which suppresses replication and transcription deficiency in gyrB-ts mutants shifted to a nonpermissive temperature. The compensatory effect of an altered subunit B of RNA polymerase (rpoB) for the gyrB defect, indicates that transcription is a primary target o
