Changes in translational accuracy of Escherichia coli when folate metabolism is perturbed.

Abstract excerpt

Translational accuracy was monitored in Escherichia coli mutants which contain abnormal folate pools. A decrease in translational accuracy was indicated by the increased production of a T4 phage mutant containing a UGA mutation in a tail fibre gene. An E. coli folC mutant suppressed the phage mutant under conditions where it presumably accumulated methyl-tetrahydrofolate (methyl-THF). A UGA suppressor strain with...
