#Celldivision protein FtsK coordinates bacterial #chromosome segregation and daughter cell separation in #Staphylococcus #aureus
Helena Veiga, Mariana Pinho et al show #FtsK interacts with the #chaperone #Triggerfactor and establishes its gradient towards the #septum to promote stability and export of the #peptidoglycan #hydrolase Sle1.

How to resist a #phage ...

This fascinating new research explores how Gram positive #bacteria (Listeria monocytogenes) can escape #bacteriophage infection by enzymatic degradation of their own bacterial cell wall #peptidoglycan to form a transient and reversible cell-wall deficient L-form removing cell wall targets used by the phage for attachment.
