Expression of recA gene of deinococcus radiodurans in escherichia coli cells

Expression of recA gene of deinococcus radiodurans in escherichia coli cells. Verbenko, V., Kuznetsova, L., Krupyan, E., & Shalguev, V. Russian Journal of Genetics, 45(10):1192-1199, 2009. cited By 3

Paper doi abstract bibtex

Plasmids pKS5 and pKSrec30 carrying normal and mutant alleles of the Deinococcus recA gene controlled by the lactose promoter slightly increase radioresistance of Escherichia coli cells with mutations in genes recA and ssb. The RecA protein of D. radiodurans is expressed in E. coli cells, and its synthesis can be supplementary induced. The radioprotective effect of the xenologic protein does not exceed 1.5 fold and yields essentially to the contribution of plasmid pUC19-recA1.1 harboring the E. coli recA+ gene in the recovery of resistance of the ΔrecA deletion mutant. These data suggest that the expression of D. radiodurans recA gene in E. coli cells does not complement mutations at gene recA in the chromosome possibly due to structural and functional peculiarities of the D. radiodurans RecA protein. © Pleiades Publishing, Inc., 2009.
