Abstract
Nonsense suppression by supE44 has been examined in a collection of 14 T4 gene 22 and gene 23 UAG mutants, for which the precise gene location is known. In concordance with previous studies, UAG followed by a pyrimidine was inefficiently suppressed. However, among positions with similar 3′ nucleotides, there was considerable variation in suppression efficiency. The competition between supE44 and Release Factor 1 (RF1) was also investigated following the introduction of a multicopy RF1 plasmid. An inverse relationship between the efficiency of suppression and RF1 competition was observed.This publication has 14 references indexed in Scilit:
