The role of active mRNA-ribosome dynamics and closing constriction in daughter chromosome separation in Escherichia coli

Chathuddasie I. Amarasinghe, Mu-Hung Chang, Jaana Männik…·Jaan Männik

This study investigates how mRNA-ribosome dynamics and division septum mechanics contribute to daughter chromosome separation in E. coli, finding that while ribosome aggregation aids separation, other forces also play a role.

Determining the rate-limiting processes for cell division in Escherichia coli

Jaana Männik, Prathitha Kar, Chathuddasie I. Amarasinghe…·Jaan Männik

This study investigates the role of FtsN and FtsA in E. coli cell division and finds that FtsZ protofilaments, not FtsN, are rate-limiting for division onset.
