MroQ Is a Novel Abi-Domain Protein That Influences Virulence Gene Expression in <i>Staphylococcus aureus</i> via Modulation of Agr Activity

Abstract

Numerous factors have, to date, been identified as playing a role in the regulation of Agr activity in Staphylococcus aureus , including transcription factors, antisense RNAs, and host elements. Herein we investigated the product of SAUSA300_1984 (termed MroQ), a transmembrane Abi-domain/M79 protease-family protein, as a novel effector of this system.
