Temperature-dependent regulation of bacterial cell division hydrolases by the coordinated action of a regulatory RNA and the ClpXP protease

Viktor Hundtofte Mebus, Larissa Milena Busch, Morten Børre…·Dorte Frees

This study identifies a temperature-sensitive regulatory mechanism in Staphylococcus aureus involving an RNA and ClpXP protease that controls cell division hydrolases.

The Spx stress regulator confers high-level β-lactam resistance and decreases susceptibility to last-line antibiotics in methicillin resistant Staphylococcus aureus

Tobias K. Nielsen, Ida Birkjær Petersen, Lijuan Xu…·Dorte Frees

This study identifies Spx as a stress regulator that enhances β-lactam resistance and reduces susceptibility to last-line antibiotics in MRSA through a redox-independent mechanism.
