[Multi-origin usage for chromosome replication of suppressive integration strain of dnaA46 mutant of Escherichia coli integrated with R6K].

Abstract excerpt

The chromosome of temperature sensitive initiation mutant dnaA46 of Escherichia coli K-12 fails to replicate at 42 degrees C. Suppressive integration (Sin) strain integrated with the R6K plasmid was screened at 42 degrees C. Marker frequency determination of the Sin strain reveals that replication was initiated at the normal site of initiation at 30 degrees C, while at three different sites at 42 degrees C. Two...
