Overproduction of DnaE protein (alpha subunit of DNA polymerase III) restores viability in a conditionally inviable Escherichia coli strain deficient in DNA polymerase I.

abstract：:In this report, we describe some of the characteristics of the Comamonas testosteroni B-356 biphenyl (BPH)-chlorobiphenyl dioxygenase system, which includes the terminal oxygenase, an iron-sulfur protein (ISPBPH) made up of an alpha subunit (51 kDa) and a beta subunit (22 kDa) encoded by bphA and bphE, respectively; a...
