Hypothesis

HBP35 is translocated to the cell surface via the Por secretion system and is glycosylated with A-LPS.

Conclusion

HBP35 is secreted via the PorSS and glycosylated on the cell surface, with the C-terminal 22 amino acids being crucial for this process.

Supporting Evidence

  • HBP35 is translocated to the cell surface via the PorSS.
  • The C-terminal 22 amino acids of HBP35 are required for its cell surface localization.
  • Glycosylation of HBP35 occurs after the removal of its C-terminal domain.

Takeaway

The study shows that a protein called HBP35 in a type of bacteria is moved to the surface and modified in a specific way, which is important for how the bacteria work.

Methodology

The study involved immunoblot analysis, deletion analysis, and GFP fusion studies to investigate the secretion and glycosylation mechanisms.
