Screening a library of temperature-sensitive mutants to identify secretion factors in Staphylococcus aureus

Journal of Bacteriology
Protein secretion is an essential cell process in bacteria, required for cell envelope biogenesis, export of virulence factors, and acquisition of nutrients, among other important functions. In the Sec secretion pathway, signal peptide-bearing precursors

Inhibitory activities of monoclonal antibodies against Staphylococcus aureus clumping factor A

mBio
Staphylococcus aureus infection is a frequent cause of sepsis in humans, a disease associated with high mortality and without specific intervention. Clumping factor A (ClfA) displayed on the bacterial surface plays a key role in promoting S.

A SecA-associated protease modulates the extent of surface display of staphylococcal protein A

Journal of Bacteriology
In bacteria, signal peptides direct pre-proteins to the SecYEG secretion channel and are typically cleaved by signal peptidases during translocation across the membrane.

Bruce Ricketts [PDF]

Psychiatric Bulletin, 1999
His formative years were spent in the Malvern Hills, Worcestershire, an area which always held a deep affection for him and played a part in his musical development. Another strong influence on him was the Quaker school he attended there. Anyone who knew Bruce can vouch for his strong sense of right and wrong and the importance of each individual.

The signal peptide of staphylococcal protein A alters the multimeric states of PepV

Microbiology Spectrum
Signal peptides (SPs) have traditionally been recognized as molecular address tags that direct protein translocation between subcellular compartments. However, emerging evidence suggests that they serve additional functions beyond their canonical role in

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

Processing of LtaS restricts LTA assembly and YSIRK preprotein trafficking into Staphylococcus aureus cross-walls

mBio
Septal membranes of Staphylococcus aureus serve as the site of secretion for precursors endowed with the YSIRK motif. Depletion of ltaS, a gene required for lipoteichoic acid (LTA) synthesis, results in the loss of restricted trafficking of YSIRK ...
