RECESSIVE LETHALS: A NEW CLASS OF NONSENSE SUPPRESSORS IN Escherichia coli*

Larry Soll 1,†, Paul Berg 1
PMCID: PMC223577  PMID: 4895537

Abstract

Two new nonsense suppressors in Escherichia coli were found in partial diploids carrying F′14 and were shown to be on the episome. These suppressors can exist only in cells which also contain the su- allele, i.e., su+/su- heterozygotes. Presumably the mutations cause an alteration of an essential cellular component, the complete loss of which is lethal. Su7, an amber suppressor, has an efficiency of 76 per cent and su8, an ochre suppressor, an efficiency of 4 per cent.
