Single-molecule imaging of DNA gyrase activity in living Escherichia coli

This study uses single-molecule imaging to analyze DNA gyrase activity in live E. coli, showing gyrase dynamics and supercoil regulation during replication.

Asymmetric MukB ATPases are regulated independently by the N- and C-terminal domains of MukF kleisin

The paper shows that MukF's N- and C-terminal domains independently regulate the two MukB ATPases in the MukBEF complex, forming an asymmetric tripartite structure during ATP cycles.
