Homodimerization and heterodimerization requirements of Acinetobacter baumannii SOS response coregulators UmuDAb and DdrR revealed by two-hybrid analyses.

Canadian journal of microbiology - 1 May 2021

Abstract excerpt

The multidrug-resistant pathogen Acinetobacter baumannii displays unusual control of its SOS mutagenesis genes, as it does not encode a LexA repressor, but instead employs the UmuDAb repressor and a small protein, DdrR, that is uniquely found in Acinetobacter species. We used bacterial adenylate cyclase two-hybrid analyses to determine if UmuDAb and DdrR coregulation might involve physical interactions. Neither...
