Deletion of the ribosomal protein gene rpmJ activates zntA transcription through a translation-dependent mechanism in Escherichia coli

Riko Shirakawa, Kazuya Ishikawa, Kazuyuki Furuta, Chikara Kaito

The paper shows that deleting rpmJ in E. coli increases zntA transcription via a translation-dependent mechanism involving early zntA mRNA translation.

Overexpression of Ribosomal Proteins Leads to Zn Resistance in Escherichia coli

Tomoki Kosaki, Riko Shirakawa, Kazuya Ishikawa…·Chikara Kaito

This study shows that overexpressing 48 out of 54 ribosomal proteins in E. coli confers Zn resistance, dependent on ZntA and Lon protease.
