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

D. Lechardeur, V. Saillant, L. Morey, D. Lipuma, P. Boëton, 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.

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

V. Saillant, D. Lipuma, E. Ostyn, L. Joubert, A. Boussac, H. Guerin, G. Brandelet, P. Arnoux, 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.

Simple rules govern the diversity of bacterial nicotianamine-like metallophores

C. Laffont, C. Brutesco, C. Hajjar, G. Cullia, R. Fanelli, L. Ouerdane, F. Cavelier, P. Arnoux

The paper identifies two simple rules governing the diversity of bacterial metallophores by analyzing substrate specificity of CntM enzymes.

The Rhodobacter sphaeroides methionine sulfoxide reductase MsrP can reduce R- and S- diastereomers of methionine sulfoxide from a broad-spectrum of protein substrates.

L. Tarrago, S. Grosse, M. I. Siponen, D. Lemaire, B. Alonso, G. Miotello, J. Armengaud, P. Arnoux, D. Pignol, M. Sabaty

This study investigates the substrate specificity of Rhodobacter sphaeroides MsrP, showing it reduces both R- and S-diastereomers of methionine sulfoxide from a broad range of periplasmic proteins.
