Mechanism of trans-envelope bacterial polysaccharide secretion in Class-3 outer-membrane polysaccharide export (OPX) protein systems - Nature Communications Bacteria secrete polysaccharides essential for colonization and infections. Here, the authors reveal the structure and mechanism of WzaB, a Class-3 OPX protein, uncovering a distinct trans-envelope se...

How do bacteria🦠polymerize sugars at the IM, but then get them out of the cell?
Answer: OPX proteins in the periplasm interfacing with OM and IM components!

Found a printed copy at home of one of my recent grant proposals, figured I could use it as tinder to light the wood stove. Worked like a charm! Although, there's something very "à propos" about watching your proposed research project go up in flames... 🔥🔥🔥

Microbial Primer: Biosurfactants – the ABCs of microbial surface-active metabolites Microbial surfactants (biosurfactants) are low-molecular-weight amphiphilic secondary metabolites synthesized by a wide range of micro-organisms, including bacteria, yeasts and fungi. These compounds ...

What to know more about #biosurfactants but do not know where to start? We are publishing a «Primer» on the topic! Great contribution from PhD student Maude Dagenais Roy www.microbiologyresearch.org/content/jour... Thanks to @microbiologysociety.org

Thanks Cynthia! If by "minor", you mean "paradigm-busting", then no worries at all! FYI, you're more than welcome to foray-on-over in the future 🦠🧫🔬
