The cloned xylE gene encoding catechol 2,3-dioxygenase (metapyrocatechase) from TOL plasmid in Pseudomonas putida mt-2 has been expressed in Escherichia coli W3110 to a level of {small...
Gomada, Manabu, Imaishi, Hiromasa, Miura, Koshiro, Inouye, Sachiye, Nakazawa, Teruko, Nakazawa, Atsushi
The transcription of both the upper operon (OPl) coding for m-xylene-degrading enzymes and the positive regulatory gene xylS on the TOL plasmid depends on cr54-RNA polymerase and requires the...
Positive regulation of the colicin E1 gene by cyclic AMP and cyclic AMP receptor protein (1985)
Shirabe, Komei, Ebina, Yousuke, Miki, Toru, Nakazawa, Teruko, Nakazawa, Atsushi
In previous experiments, we showed that the in vivo transcription of the colicin E1 gene was dependent on cyclic AMP in adenylate cyclase-defective mutant cells of Escherichia coil (Ebina, Y. and...
KISHI, Fumio, EBINA, Yousuke, MIKI, Toru, NAKAZAWA, Teruko, NAKAZAWA, Atsushi
From the cells of an Escherichia coli K-12 strain, a 22,000-dalton protein which has an affinity for the superhelical DNA molecule was purified to apparent homogeneity by monitoring the DNA-binding...
Gene expression in vitro of colicin E1 plasmid (1979)
Ebina, Yousuke, Kishi, Fumio, Nakazawa, Teruko, Nakazawa, Atsushi
Among eighteen polypeptides synthesized in vitro from colicin El plasmid, one of the major products with a molecular weight of 59,000 was identified as colicin El by its immunological property,...
In Vitro Anti-Helicobacter pylori Activities of New Rifamycin Derivatives, KRM-1648 and KRM-1657
Akada, Junko K., Shirai, Mutsunori, Fujii, Kenji, Okita, Kiwamu, Nakazawa, Teruko
The new rifamycin derivatives KRM-1657 and KRM-1648 were evaluated for their in vitro antimicrobial activities against 44 strains of Helicobacter pylori. Although the drugs were not very active...

Lymphotoxin Inhibits Chlamydia pneumoniae Growth in HEp-2 Cells
Matsushima, Hiroshi, Shirai, Mutsunori, Ouchi, Kazunobu, Yamashita, Kenji, Kakutani, Tetsu, Furukawa, Susumu, ...
Cytokines such as gamma interferon and tumor necrosis factor alpha (TNF-α) inhibit the intracellular replication of Chlamydia pneumoniae or Chlamydia trachomatis. In this study, we found that...
Comparison of whole genome sequences of Chlamydia pneumoniae J138 from Japan and CWL029 from USA

Takeuchi, Hiroaki, Shirai, Mutsunori, Akada, Junko K., Tsuda, Masataka, Nakazawa, Teruko
We identified cell division-related gene cdrA in Helicobacter pylori HPK5. The putative gene product, CdrA, is a 367-amino-acid polypeptide that exhibited a high level of homology to conserved...
Nakamura, Hiroki, Yoshiyama, Hironori, Takeuchi, Hiroaki, Mizote, Tomoko, Okita, Kiwamu, Nakazawa, Teruko
Helicobacter pylori exhibits chemotactic responses to urea, flurofamide, acetohydroxamic acid, and sodium bicarbonate. In buffer, the chemotactic activities of a urease-positive strain were higher...
Kersulyte, Dangeruta, Mukhopadhyay, Asish K., Shirai, Mutsinori, Nakazawa, Teruko, Berg, Douglas E.
A search by subtractive hybridization for sequences present in only certain strains of Helicobacter pylori led to the discovery of a 2-kb transposable element to be called IS607, which further PCR...
Benzoate Metabolism in Pseudomonas putida(arvilla) mt-2: Demonstration of Two Benzoate Pathways
Nakazawa, Teruko, Yokota, Takeshi
Benzoate-grown cells of Pseudomonas putida(arvilla) mt-2 contain both metapyrocatechase and pyrocatechase activities, although the former activity is much higher than that of the latter. A...
Nakazawa, Teruko, Yokota, Takeshi
Adenosine-3′, 5′-cyclic monophosphate (cyclic AMP) is essential for the synthesis of l-arabinose isomerase in Escherichia coli. Cyclic AMP appears to be required for the transcription of...
