title: Cloning of the recB, recC, and recD genes from Proteus mirabilis in Escherichia coli: in vivo formation of active hybrid enzymes.
abstract: We cloned chromosomal DNA fragments from Proteus mirabilis which complement recBCD deletion mutants of Escherichia coli by restoring (i) recombination proficiency in conjugation, (ii) normal resistance to UV irradiation, and (iii) ATP-dependent exonuclease activity for duplex DNA. The data indicate that the order of the genes thyA, recC, recB, recD, and argA is similar in both P. mirabilis and E. coli. Hybrid enzymes formed in vivo were active in repair and recombination.
