aarD, a Providencia stuartii homologue of cydD: role in 2'-N-acetyltransferase expression, cell morphology and growth in the presence of an extracellular factor.

Abstract excerpt

In a search for genes involved in regulation of the 2'-N-acetyltransferase in Providencia stuartii, a mini-Tn5Cm insertion has been isolated in a locus designated aarD. The aarD1::mini-Tn5Cm mutation resulted in a 4.7-fold increase in the levels of beta-galactosidase accumulation from an aac(2')-lacZ transcriptional fusion and a 32-fold increase in the levels of gentamicin resistance in P. stuartii. The wild-type...
