Missense mutations in the 3' end of the Escherichia coli dnaG gene do not abolish primase activity but do confer the chromosome-segregation-defective (par) phenotype.

Microbiology (Reading, England) - 1 Feb 1997

Versalovic James, Lupski James R

Abstract excerpt

Isogenic dnaG strains of Escherichia coli with the parB and dnaG2903 alleles in the MG1655 chromosomal background displayed the classic par phenotype at the nonpermissive temperature of 42 degrees C. These strains synthesized DNA at 42 degrees C, but remained chromosome segregation defective as determined by cytology. A strain with the dnaG2903 allele was tested for its ability to support DNA replication of a...
