Thanks to the Hochberg and Bange labs for the great collaboration!

Archaeal cells whose DNA has been stained with a blue dye. Zoomed-in images of mutant cells that display chromosome segregation defects.

High-resolution images of DNA-protein complexes obtained with atomic force microscopy. Upon binding, the protein bridges distant sites, forming loops.

Peptidoglycan recycling is critical for cell division, cell wall integrity and β-lactam resistance in Caulobacter crescentus Most bacteria possess a peptidoglycan sacculus, which is continuously remodeled during cell growth and division. The peptidoglycan (PG) fragments generated in this process are typically imported into ...

Repost = nice. Thank you very much!!!

Molecular basis of ParA ATPase activation by the CTPase ParB during bacterial chromosome segregation - Nature Communications ParABS systems partition chromosomal DNA and low-copy plasmids in bacteria. Here, the authors elucidate the mode of interaction between ParA and ParB and clarify how ParB stimulates the ATPase activity of ParA to drive the segregation process.
