Role of SspA in the density-dependent expression of the transcriptional activator AarP in Providencia stuartii.

FEMS microbiology letters - 1 Mar 2001

Ding X, Baca-DeLancey R R, Rather P N

Abstract excerpt

The AarP protein in Providencia stuartii encodes a small transcriptional activator which activates the chromosomal aminoglycoside acetyltransferase aac(2')-Ia gene. In addition, AarP activates genes involved in a multiple antibiotic resistance (Mar) phenotype. Expression of an aarP-lacZ fusion increased in a density-dependent manner and reached peak levels at stationary phase. The expression of an aarP-lacZ...
