Abstract
The activities of inorganic pyrophosphatase, thymidine kinase and thymidine phosphorylase were measured in Ter-mutants of E. coli K12 which have a higher or a lower dTTP pool than the parent strain. The levels of inorganic pyrophosphatase and thymidine kinase were changed in the same direction and that of thymidine phosphorylase in the opposite direction in these mutants.
