Abstract

A plasmid carrying the Deinococcus radiodurans recX gene under the control of a lactose promoter decreases the Escherichia coli cell resistance to UV irradiation and γ irradiation and also influences the conjugational recombination process. The D. radiodurans RecX protein functions in the Escherichia coli cells similarly to the E. coli RecX protein. Isolated and purified D. radiodurans RecX and E. coli RecX proteins are able to replace each other interacting with the E. coli RecA and D. radiodurans RecA proteins in vitro. Data obtained demonstrated that regulatory interaction of RecA and RecX proteins preserves a high degree of conservatism despite all the differences in the recombination reparation system between E. coli and D. radiodurans.
