Masai, H and Arai, K (1989) Escherichia coli dnaT gene function is required for pBR322 plasmid replication but not for R1 plasmid replication. J. Bacteriol. 171:2975-80

Abstract

Plasmid pBR322 was unable to replicate in a temperature-sensitive dnaT1 strain at a nonpermissive temperature, whereas a pBR322-derived plasmid carrying the wild-type dnaT+ gene was able to replicate under the same conditions. In contrast to pBR322, plasmid R1 could replicate in the dnaT1 strain at a nonpermissive temperature. In keeping with this finding, in vitro replication of plasmid R1 did not require DnaT protein.
