Journal ArticleDOI
Extracellular proteases are key mediators of Staphylococcus aureus virulence via the global modulation of virulence-determinant stability.
Stacey L. Kolar,J. Antonio Ibarra,Frances E. Rivera,Joe M. Mootz,Jessica E. Davenport,Stanley M. Stevens,Alexander R. Horswill,Lindsey N. Shaw +7 more
TL;DR: It is shown that exo‐proteases are required for growth in peptide‐rich environments, serum, in the presence of antimicrobial peptides (AMPs), and in human blood, and that extracellular proteases are important for resisting phagocytosis by human leukocytes.
Journal ArticleDOI
NsaRS is a Cell-Envelope-Stress-Sensing two-Component System of Staphylococcus Aureus
Stacey L. Kolar,Vijayaraj Nagarajan,Anna Oszmiana,Frances E. Rivera,Halie K. Miller,Jessica E. Davenport,James T. Riordan,Jan Potempa,David S. Barber,Joanna Koziel,Mohamed O. Elasri,Lindsey N. Shaw +11 more
TL;DR: A characterization of NsaRS is presented and it is revealed that it responds to disruptions in the cell envelope and functions to reprogram gene expression to modify cell envelope architecture, facilitating adaptation and survival.
Journal ArticleDOI
The impact of CodY on virulence determinant production in community-associated methicillin-resistant Staphylococcus aureus.
TL;DR: The power of mass spectrometry‐based quantitative proteomics for studying toxin production in S. aureus, and the importance of CodY to this central process in disease causation and infection are demonstrated.
Journal ArticleDOI
Identification of an intracellular M17 family leucine aminopeptidase that is required for virulence in Staphylococcus aureus
Ronan K. Carroll,Tiffany M. Robison,Frances E. Rivera,Jessica E. Davenport,Ing-Marie Jonsson,Danuta Florczyk,Andrej Tarkowski,Jan Potempa,Jan Potempa,Joanna Koziel,Lindsey N. Shaw +10 more
TL;DR: For the first time an intracellular leucine aminopeptidase (LAP, pepZ) is identified that influences disease causation in a Gram-positive bacterium.
Journal ArticleDOI
Contribution of the nos-pdt Operon to Virulence Phenotypes in Methicillin-Sensitive Staphylococcus aureus
April M. Sapp,Austin B. Mogen,Erin A. Almand,Frances E. Rivera,Lindsey N. Shaw,Anthony R. Richardson,Kelly C. Rice +6 more
TL;DR: In this paper, the NO-synthase (saNOS) enzyme encoded by the nos gene was found to increase during lowoxygen growth and is growth-phase dependent.
