ProteomicsProteolytic activity of surface exposed HtrA determines its expression level and is needed to survive acidic conditions in Clostridioides difficile
To survive in the host, pathogenic bacteria need to be able to react to the unfavourable conditions that they encounter, like low pH, elevated temperatures, antimicrobial peptides and many more. These conditions may lead to unfolding of envelope proteins and this may be lethal. One of the mechanisms...

ProteomicsMembrane substrates of HtrA from Helicobacter pylori
High temperature requirement A (HtrA) is a serine protease secreted by the group-I carcinogen Helicobacter pylori (H. pylori). The human cell adhesion protein and tumor suppressor E-cadherin (hCdh1) expressed on the surface of gastric epithelial cells was identified as the first HtrA substrate. HtrA...

TranscriptomicsThe HtrA chaperone monitors sortase-assembled pilus biogenesis in E. faecalis
Sortase-assembled pili contribute to virulence in many Gram-positive bacteria. In Enterococcus faecalis, the endocarditis and biofilm-associated pilus (Ebp) is polymerized on the membrane by sortase C (SrtC) and attached to the cell wall by sortase A (SrtA). In the absence of SrtA, polymerized pili ...
