Thus , OmpR represses cadC/BA by directly binding to upstream DNA at cadB .
Importantly , a recent study suggests that Salmo-nella OmpR represses the cadC/BA operon by directly binding to both cadB promoters in SCV of macrophages .
Importantly , a recent study suggests that Salmo-nella OmpR represses the cadC/BA operon by directly binding to both cadB promoters in the Salmonellacontaining vacuole of macrophages .
Activated OmpR then represses the cadC/BA operon by directly binding to both cadB promo-ters , leading to cytoplasmic acidification .
