Journal ArticleDOI
The M1- and M2-type isozymes of rat pyruvate kinase are produced from the same gene by alternative RNA splicing.
TL;DR: It is concluded that the M1- and M2-type isozymes of pyruvate kinase are produced from the same gene probably by alternative RNA splicing.
Journal ArticleDOI

TL;DR: The structural changes in PSII induced by two-flash illumination at room temperature at a resolution of 2.35 Å are described, providing a mechanism for the O=O bond formation consistent with that proposed previously.
Journal ArticleDOI
Vibrational Spectra and Ab Initio DFT Calculations of 4-Methylimidazole and Its Different Protonation Forms: Infrared and Raman Markers of the Protonation State of a Histidine Side Chain
TL;DR: In this paper, normal mode calculations using density function theory (DFT) method for all four protonation forms of 4-methylimidazole (a simple model compound of a histidine side chain) and their N-deuterated analogues were performed.
Journal ArticleDOI
X-ray Detection of the Period-Four Cycling of the Manganese Cluster in Photosynthetic Water Oxidizing Enzyme
Taka aki Ono,Takumi Noguchi,Yorinao Inoue,Masami Kusunoki,Tadashi Matsushita,Hiroyuki Oyanagi +5 more
TL;DR: X-ray absorption near-edge structure spectra of the manganese (Mn) cluster in physiologically native intermediate states of photosynthetic water oxidation induced by short laser flash suggest that the Mn cluster is oxidized by one electron upon the S0-to-S1, S1- to-S2, and S2-to -S3 transitions and then reduced upon a transition that releases molecular oxygen.
Journal ArticleDOI
Flash-Induced FTIR Difference Spectra of the Water Oxidizing Complex in Moderately Hydrated Photosystem II Core Films: Effect of Hydration Extent on S-State Transitions†
Takumi Noguchi,Miwa Sugiura +1 more
TL;DR: The results showed that moderate hydration of the PSII sample made the whole OH region measurable, escaping from absorption saturation by bulk water, and thus will be a useful technique to monitor the water reactions during the S-state cycle using FTIR spectroscopy.
