Activation of the 2'-N-acetyltransferase gene [aac(2')-Ia] in Providencia stuartii by an interaction of AarP with the promoter region.
The aac(2')-Ia gene in Providencia stuartii encodes a 2'-N-acetyltransferase capable of acetylating both peptidoglycan and certain aminoglycoside antibiotics. Regulation of the aac(2')-Ia gene is influenced in a positive manner by the product of the aarP gene, which encodes a small transcriptional activator of the AraC (XylS) family. In this study, we demonstrate the sequence requirements at the aac(2')-Ia promoter for AarP binding and activation.
