Transcription factor distribution in Escherichia coli: studies with FNR protein (2007)

Grainger, David C., Aiba, Hirofumi, Hurd, Douglas, Browning, Douglas F., Busby, Stephen J. W.

Using chromatin immunoprecipitation (ChIP) and high-density microarrays, we have measured the distribution of the global transcription regulator protein, FNR, across the entire Escherichia coli...

Escherichia coli Histone-Like Protein H-NS Preferentially Binds to Horizontally Acquired DNA in Association with RNA Polymerase (2006)

Oshima, Taku, Ishikawa, Shu, Kurokawa, Ken, Aiba, Hirofumi, Ogasawara, Naotake

Heat-stable nucleoid-structuring protein (H-NS) is one of the main nucleoid proteins expressed in exponentially growing Escherichia coli cells. In addition to a role in nucleoid organization, H-NS...

The Arabidopsis Sensor His-kinase, AHK4, Can Respond to Cytokinins (2001)

Suzuki, Tomomi, Miwa, Kumiko, Ishikawa, Kuniko, Yamada, Hisami, Aiba, Hirofumi, Mizuno, Takeshi

His-to-Asp (His→Asp) phosphorelay mechanisms are presumably involved in propagation of certain environmental stimuli, including phytohormones, in Arabidopsis thaliana. In addition to the previously...

A Fission Yeast Gene (prrl+) That Encodes a Response Regulator Implicated in Oxidative Stress Response (1999)

Ohmiya, Ryusuke, Kato, Chinatsu, Yamada, Hisami, Aiba, Hirofumi, Mizuno, Takeshi

An inspection of the Schizosaccharomyces pombe genome database revealed that this eukaryotic microorganism possesses a gene that may encode a bacterial type of histidine-to-aspartate (His-Asp)...

Transmembrane Signal Transduction and Osmoregulation in Escherichia coli: I. Analysis by Site-Directed Mutagenesis of the Amino Acid Residues Involved in Phosphotransfer between the Two Regulatory Components, EnvZ and OmpR (1990)

Kanamaru, Kengo, Aiba, Hirofumi, Mizuno, Takeshi

Previously, the transfer of a phosphoryl group between the EnvZ and OmpR proteins, which are involved in expression of the ompF and ompC genes in response to the medium osmolarity, was demonstrated...

Transmembrane Signal Transduction and Osmoregulation in Escherichia coli: II. The Osmotic Sensor, EnvZ, Located in the Isolated Cytoplasmic Membrane Displays Its Phosphorylation and Dephosphorylation Abilities as to the Activator Protein, OmpR (1990)

Tokishita, Shin-ichi, Yamada, Hisami, Aiba, Hirofumi, Mizuno, Takeshi

The EnvZ protein is presumably a membrane-located osmotic sensor, which specifically phosphorylates the activator protein, OmpR, involved in expression of the ompF and ompC genes in Escherichia coli....

Phosphorylation of a Bacterial Activator Protein, OmpR, by a Protein Kinase, EnvZ, Results in Stimulation of Its DNA-Binding Ability (1989)

Aiba, Hirofumi, Nakasai, Fujie, Mizushima, Shoji, Mizuno, Takeshi

The Escherichia coli OmpR protein is an activator protein specific for the ompF and ompC genes, which respectively encode the outer membrane proteins, OmpF and OmpC. The EnvZ protein is a protein...

Isolation and Characterization of High-Osmolarity-Sensitive Mutants of Fission Yeast

Aiba, Hirofumi, Kawaura, Ryosuke, Yamamoto, Eiji, Yamada, Hisami, Takegawa, Kaoru, Mizuno, Takeshi

For the fission yeast Schizosaccharomyces pombe, adaptation to high-osmolarity medium is mediated by a mitogen-activated protein (MAP) kinase cascade, involving the Wis1 MAP kinase kinase and the...
