Fifteen actinomycetes were isolated from deep-sea sediments in Calyptogena communities in the Japan Trench (depth: 5352 m) and Sagami Bay (depth: 1171 m) under incubation at 4–37 °C. A relatively large number of colonies were obtained with incubat

Absorption changes in Photosystem II in the Soret band region upon the formation of the chlorophyll cation radical [PD1PD2]+

Autor: Alain Boussac, Miwa Sugiura, Makoto Nakamura, A. William Rutherford, Stefania Viola, Julien Sellés

Flash-induced absorption changes in the Soret region arising from the [PD1PD2]+ state, the chlorophyll cation radical formed upon excitation of Photosystem II (PSII), were obtained using Mn-depleted PSII cores at pH 8.6. Under these conditions, TyrD

International audience; Electrochromic band-shifts have been investigated in Photosystem II (PSII) from Thermosynechoccocus elongatus. Firstly, by using Mn-depleted PsbA1-PSII and PsbA3-PSII in which the QX absorption of PheD1 differs, a band-shift i

Mechanism of Proton-Coupled Electron Transfer in the S0-to-S1 Transition of Photosynthetic Water Oxidation As Revealed by Time-Resolved Infrared Spectroscopy

Autor: Tatsuki Shimizu, Takumi Noguchi, Miwa Sugiura

Publikováno v: The Journal of Physical Chemistry B. 122:9460-9470

Photosynthetic water oxidation takes place at the Mn4CaO5 cluster in photosystem II through a light-driven cycle of intermediates called S states (S0–S4). To unravel the mechanism of water oxidation, it is essential to understand the coupling of el
