[Cloning and sequencing of the chromosome fragment of Bacillus subtilis, complementary to the exoA mutation of Bacillus subtilis and sbcB of Escherichia coli].

Abstract excerpt

A 3279-bp fragment of the Bacillus subtilis chromosome was cloned. This fragment completely restored exonuclease I activity in cells of the Escherichia coli Jm105 strain, which contained the sbcB mutation, and suppressed repair damage in cells of this mutant. The cloned fragment fully complemented a mutation that decreased exonuclease I activity in Bac. subtilis KU647 and KU1020 strains leading to the restoration...
