Lack of Light/Dark Regulation of Enzymes Involved in the Photosynthetic Carbon Reduction Cycle in Cyanobacteria, Synechococcus PCC 7942 and Synechocystis PCC 6803
Tamoi M, Murakami A, Takeda T, Shigeoka S
Biosci Biotechnol Biochem . 2016 Jul; 62(2):374-6. PMID: 27388521
During the photosynthetic carbon reduction (PCR) cycle of Synechococcus PCC 7942 and Synechocystis PCC 6803, fructose-1,6-bisphosphatase, NADP(+)-glyceraldehyde-3-phosphate dehydrogenase, and ribulose-5-phosphate kinase were not sensitive to treatment with dithiothreitol (DTT), a...

[Identification system for Sildenafil in health foods]
Moriyasu T, Shigeoka S, Kishimoto K, Ishikawa F, Nakajima J, Kamimura H, et al.
Yakugaku Zasshi . 2001 Oct; 121(10):765-9. PMID: 11676179
A substantially available identification system for Sildenafil in health foods was established using 3 different analytical methods; i.e. TLC, preparative TLC/MS and HPLC/photo-diode array. Sildenafil in health foods was extracted...

Overexpression of a cyanobacterial fructose-1,6-/sedoheptulose-1,7-bisphosphatase in tobacco enhances photosynthesis and growth
Miyagawa Y, Tamoi M, Shigeoka S
Nat Biotechnol . 2001 Oct; 19(10):965-9. PMID: 11581664
Transgenic tobacco plants expressing a cyanobacterial fructose-1,6/sedoheptulose-1,7-bisphosphatase targeted to chloroplasts show enhanced photosynthetic efficiency and growth characteristics under atmospheric conditions (360 p.p.m. CO2). Compared with wild-type tobacco, final dry matter...

NADPH-dependent glutathione peroxidase-like proteins (Gpx-1, Gpx-2) reduce unsaturated fatty acid hydroperoxides in Synechocystis PCC 6803
Gaber A, Tamoi M, Takeda T, Nakano Y, Shigeoka S
FEBS Lett . 2001 Jun; 499(1-2):32-6. PMID: 11418106
Here we isolated and characterized two genes (slr1171, slr1992) designated gpx-1 and gpx-2, respectively, encoding glutathione peroxidase (GPX)-like proteins (Gpx-1, Gpx-2) from Synechocystis PCC 6803. The deduced amino acid sequences...

Molecular mechanisms of the resistance to hydrogen peroxide of enzymes involved in the calvin cycle from halotolerant Chlamydomonas sp. W80
Tamoi M, Kanaboshi H, Miyasaka H, Shigeoka S
Arch Biochem Biophys . 2001 Jun; 390(2):176-85. PMID: 11396920
cDNA clones encoding NADP(+)-glyceraldehyde-3-phosphate dehydrogenase (NADP(+)-GAPDH) and sedoheptulose-1,7-bisphosphatase (SBPase) were isolated and characterized from halotolerant Chlamydomonas sp. W80 (C. W80) cells. The cDNA clone for NADP(+)-GAPDH encoded 369 amino acid...

Crystallization and preliminary X-ray diffraction analysis of NADP-dependent glyceraldehyde-3-phosphate dehydrogenase of Synechococcus PCC 7942
Nakamura Y, Tada T, Wada K, Kinoshita T, Tamoi M, Shigeoka S, et al.
Acta Crystallogr D Biol Crystallogr . 2001 May; 57(Pt 6):879-81. PMID: 11375515
The NADP-dependent glyceraldehyde-3-phosphate dehydrogenase (GAPDH) of Synechococcus PCC 7942 was crystallized in two different forms by the hanging-drop vapour-diffusion method using ammonium sulfate as a precipitant. Form I crystals were...

Characterization of ascorbate peroxidases from unicellular red alga Galdieria partita
Sano S, Ueda M, Kitajima S, Takeda T, Shigeoka S, Kurano N, et al.
Plant Cell Physiol . 2001 May; 42(4):433-40. PMID: 11333315
Galdieria partita, a unicellular red alga isolated from acidic hot springs and tolerant to sulfur dioxide, has at least two ascorbate peroxidase (APX) isozymes. This was the first report to...

Characterization of monoclonal antibodies against ascorbate peroxidase isoenzymes: purification and epitope-mapping using immunoaffinity column chromatography
Yoshimura K, Ishikawa T, Wada K, Takeda T, Kamata Y, Tada T, et al.
Biochim Biophys Acta . 2001 Apr; 1526(2):168-74. PMID: 11325538
We have developed three monoclonal antibodies against spinach chloroplastic (chl-mAb3 and chl-mAb6) and cytosolic (cyt-mAb1) ascorbate peroxidase (APX) isoenzymes to analyze the cross-reactivity and the structure of the epitopes for...
