ABSTRACT
A temperature-sensitive dnaB mutation, dnaB125, was shown to be a suppressed amber mutation. The effects of inserting different amino acids at the mutated site via amber suppressors were examined for both Escherichia coli and bacteriophage gamma growth. In addition, the dnaB125 amber allele was shown to be different from the previously described dnaB amber allele, dnaB266. The extent of residual deoxyribonucleic acid synthesis observed in a supF(Ts) dnaB125 strain at high temperature revealed that the dnaB protein was present in excess and that deoxyribonucleic acid synthesis could continue for several generation equivalents without further production of dnaB protein.
