Differential effects of ethanol and the rpsL1 (strA1) ribosomal mutation on the synthesis of an unusual protein coded by bacteriophages R17 and MS2 RNA

During translation of R17 and MS2 RNA, ethanol stimulates the synthesis of a coat-related protein which has identical electrophoretic mobility to that of polypeptide 7 studied by Atkins and his colleagues. Streptomycin stimulates the synthesis of this polypeptide and broadens the protein band. In contrast the ribosomal protein S12 mutation rpsL1 (strA1) has no detectable effect on its synthesis.
