A membrane-depolarising toxin substrate of the Staphylococcus aureus Type VII secretion system mediates intra-species competition

F. R. Ulhuq, M. C. Gomes, G. Duggan, M. Guo, C. Mendonca, G. Buchanan, J. D. Chalmers, Z. Cao, H. Kneuper, S. Murdoch, S. Thomson, H. Strahl, M. Trost, S. Mostowy, T. Palmer

This paper identifies TspA as a new T7SS substrate in S. aureus, showing it mediates intra-species competition by membrane depolarization and growth inhibition in vivo.

Controlling and co-ordinating chitinase secretion in a Serratia marcescens population

M. d. A. A. Costa, R. A. Owen, T. Tammsalu, G. Buchanan, T. Palmer, F. Sargent

This paper investigates the role of ChiR in coordinating chitinase secretion and bimodal gene expression in S. marcescens, showing that ChiR increases chitinase expression in over 60% of the population and links chitin breakdown to nitrogen metabolism.

EsaB is a core component of the Staphylococcus aureus Type VII secretion system

M. G. Casabona, G. Buchanan, M. Zoltner, C. P. Harkins, M. T. G. Holden, T. Palmer

This study shows EsaB is essential for T7SS secretion in S. aureus but not for substrate production, and has both T7SS-dependent and -independent roles.

A unifying mechanism for the biogenesis of prokaryotic membrane proteins co-operatively integrated by the Sec and Tat pathways

T. Palmer, F. J. Tooke, M. Babot, G. Chandra, G. Buchanan

This paper identifies a unifying mechanism for the biogenesis of prokaryotic membrane proteins that require both Sec and Tat pathways for insertion, showing that low hydrophobicity and C-terminal charges dictate Sec release.
