Role of HPF (Hibernation Promoting Factor) in Translational Activity in Escherichia coli (2008)

Ueta, Masami, Ohniwa, Ryosuke L., Yoshida, Hideji, Maki, Yasushi, Wada, Chieko, Wada, Akira

During the stationary phase of growth in Escherichia coli, ribosome modulation factor (RMF) and hibernation promoting factor (HPF) dimerize most 70S ribosomes to form 100S ribosomes. The process of...

Dynamic state of DNA topology is essential for genome condensation in bacteria

Ohniwa, Ryosuke L, Morikawa, Kazuya, Kim, Joongbaek, Ohta, Toshiko, Ishihama, Akira, Wada, Chieko, ...

In bacteria, Dps is one of the critical proteins to build up a condensed nucleoid in response to the environmental stresses. In this study, we found that the expression of Dps and the nucleoid...
