HssS activation by membrane heme defines a paradigm for 2-component system signaling in Staphylococcus aureus.

D. Lechardeur, V. Saillant, L. Morey…·P. Arnoux

This study identifies how heme binds to the HssS sensor in Staphylococcus aureus, triggering a signaling cascade that activates heme efflux to prevent toxicity.

Two functionally distinct heme/iron transport systems are virulence determinants of the fish pathogen Flavobacterium psychrophilum

Y. Zhu, D. Lechardeur, J.-F. Bernardet…·T. Rochat

This study identifies two heme/iron transport systems in Flavobacterium psychrophilum that are essential for virulence and adaptation to iron conditions during infection.

A novel Enterococcus faecalis heme transport regulator (FhtR) is a heme sensor in the gastrointestinal tract.

V. Saillant, D. Lipuma, E. Ostyn…·D. Lechardeur

This paper identifies FhtR as a heme sensor in E. faecalis that regulates heme homeostasis by controlling an efflux pump and catalase expression in the gastrointestinal tract.
