Photosynthetic water oxidation is catalyzed by the oxygen-evolving complex (OEC) in
photosystem II (PSII). This process is energetically driven by light-induced charge separation …

Detailed comparative studies of flash induced oxygen evolution patterns in thylakoids from
the thermophilic cyanobacterium Synechococcus elongatus (S. elongatus; also referred to …

The oxidation of water into molecular oxygen during photosynthesis is catalyzed by a
subdomain of photosystem II (PSII) termed the water oxidizing complex (WOC). Contained …

The oxygen-evolving complex of Photosystem II cycles through five oxidation states (S 0–S
4), and dark incubation leads to 25% S 0 and 75% S 1. This distribution cannot be reached …

The oxygen-evolving complex (OEC) in photosystem II catalyzes the oxidation of water to
molecular oxygen. Four decades ago, measurements of flash-induced oxygen evolution …

Abstract In Photosystem II (PS II), water is oxidized to molecular oxygen and plastoquinone
is reduced to plastoquinol. The oxidation of water requires the accumulation of four oxidizing …

Photosystem II complexes of higher plants are structurally and functionally heterogeneous.
While the only clearly defined structural difference is that Photosystem II reaction centers are …

In oxygenic photosynthesis, photosystem II (PSII) is the multisubunit membrane protein
responsible for the oxidation of water to O 2 and the reduction of plastoquinone to …

Photosystem II (PS II) is a light-dependent water: plastoquinone-oxidoreductase, an enzyme
that uses light energy to oxidize water (with release of oxygen and protons) and to reduce …

In this study we employ isotope ratio membrane-inlet mass spectrometry to probe the
turnover efficiency of photosystem II (PSII) membrane fragments isolated from spinach at …
