Instability of inhibited replication forks in E. coli.
Kuzminov A. Kuzminov A. Bioessays. 1995 Aug;17(8):733-41. doi: 10.1002/bies.950170810. Bioessays. 1995. PMID: 7661854 Review.
These findings explain a particular pattern of DNA degradation during inhibition of chromosomal replication, the role of recombination in the viability of mutants with displaced replication origin, and hyper-recombination observed in the Terminus of the E. coli chromosome …

Chromosomal Replication Complexity: A Novel DNA Metrics and Genome Instability Factor.
Kuzminov A. Kuzminov A. PLoS Genet. 2016 Oct 6;12(10):e1006229. doi: 10.1371/journal.pgen.1006229. eCollection 2016 Oct. PLoS Genet. 2016. PMID: 27711112 Free PMC article. Review.
To accurately describe the resulting "amplification by overinitiation," I propose a new term: "replification" (subchromosomal overreplication). In both prokaryotes and eukaryotes, replification, via sRF processing, causes double-strand DNA breaks and, with their repair ele …

RNase HII Saves rnhA Mutant Escherichia coli from R-Loop-Associated Chromosomal Fragmentation.
Kouzminova EA, Kadyrov FF, Kuzminov A. Kouzminova EA, et al. J Mol Biol. 2017 Sep 15;429(19):2873-2894. doi: 10.1016/j.jmb.2017.08.004. Epub 2017 Aug 15. J Mol Biol. 2017. PMID: 28821455 Free PMC article.
However, a plasmid relaxation test failed to detect R-tracts in DNA of the rnhAB mutants, although it readily detected R-patches (runs of 1-3 rNs). ...

Static and Dynamic Factors Limit Chromosomal Replication Complexity in Escherichia coli, Avoiding Dangers of Runaway Overreplication.
Khan SR, Mahaseth T, Kouzminova EA, Cronan GE, Kuzminov A. Khan SR, et al. Genetics. 2016 Mar;202(3):945-60. doi: 10.1534/genetics.115.184697. Epub 2016 Jan 22. Genetics. 2016. PMID: 26801182 Free PMC article.
Although a typical CRC of eukaryotic or bacterial chromosomes is 2, rapidly growing Escherichia coli cells induce an extra round of replication in their chromosomes (CRC = 4). ...Whereas recombinational repair is beneficial for cells at the natural and functional CRC limit …

Chromosome demise in the wake of ligase-deficient replication.
Kouzminova EA, Kuzminov A. Kouzminova EA, et al. Mol Microbiol. 2012 Jun;84(6):1079-96. doi: 10.1111/j.1365-2958.2012.08076.x. Epub 2012 May 14. Mol Microbiol. 2012. PMID: 22582878 Free PMC article.
Here we show that replication without ligase kills after a short resistance period. We found that double-strand break repair via RecA, RecBCD, RuvABC and RecG explains the transient resistance, whereas irreparable chromosomal fragmentation explains subsequent cell death. . …
