Boussac A, Rutherford AW, 1988, Ca<sup>2+</sup> binding to the oxygen evolving enzyme varies with the redox state of the Mn cluster, FEBS Letters, Vol: 236, Pages: 432-436, ISSN: 0014-5793

Oxygen evolution by the mangano-enzyme of photosystem II is inhibited by Ca2+ depletion induced by NaCl washing and restored by Ca2+ addition. The effectiveness of NaCl treatment in inhibiting oxygen evolution in photosystem II was studied after a series of preilluminating flashes. The susceptibility of the enzyme to NaCl treatment varied with the number of preilluminating flashes and this variation showed an oscillation pattern with a period of four. This pattern is characteristic of cycling through the four long-lived intermediate states in the enzyme cycle (i.e. the states, S0, S1, S2, S3). The relative extent of inhibition corresponding to each of the S states was as follows: S3 > S0≈S2 > S1. From these results it is concluded that Ca2+ binding is dependent on the S states and that Ca2+ probably plays a fundamental role in the mechanism of water splitting. The results also help to explain the conflicting reports of the extent of inhibition induced by NaCl washing and the controversy over which electron transfer step is inhibited by Ca2+ depletion. © 1988.

An EPR study of the low fluorescent mutant, LF1, of the green alga, Scenedesmus obliquus, has been performed and the following results were obtained. (1) Stable photoinduced charge separation occurs at low temperature forming the characteristic EPR signals from Q-AFe2+, the primary semiquinone-iron complex, indicating no major structural modification of the electron acceptor complex in the LF1 mutant. (2) The source of the electron in this reaction at 200 K is a component, probably a chlorophyll molecule, which gives rise to an EPR signal at g ≈ 2.0026 when photooxidized; in the wild type the S2 manganese multiline EPR signal is generated under these conditions. (3) Contrary to a previous report (Biochim. Biophys. Acta 682 (1982) 106-114), Signal II is present in the dark in LF1; however, it exhibits different microwave power saturation characteristics from those of Signal II in the wild type. These results show that the LF1 mutant has a functional reaction centre which lacks the redox active manganese of the O2-evolving enzyme. In addition, as reported previously, cytochrome b-559 is in the low-potential, oxidized form in LF1, while it is largely in the high-potential, reduced form in the wild-type. This effect is thought to be only indirectly related to the 34 kDa to the 36 kDa change in D1 polypeptide size, which is assumed to be responsible for the lack of Mn binding in the LF1 mutant. © 1988.

Mathis P, Rutherford AW, 1987, The Primary Reactions of Photosystems I and II of Algae and Higher Plants, New Comprehensive Biochemistry, Vol: 15, Pages: 63-96, ISSN: 0167-7306

This chapter discusses the primary reactions of photosystems I and II of algae and higher plants. In photosynthetic organisms, the “primary reactions” fulfil the objective of converting the energy of light into a primary form of chemical energy which lasts for a time compatible with ordinary biochemical processes—that is, milliseconds. In these reactions, a rather large fraction, approximately 40%, of the photon energy is stored as chemical free energy. The primary reactions can be viewed from two major perspectives. Firstly, from a photochemical point of view: pigment molecules are excited to their lowest excited singlet state, which reacts in an electron transfer reaction, the first step of a process of charge separation. Secondly, from a biochemical point of view the reactions take place in highly organized complexes, the reaction centres, which are made up of several classes of molecules that cooperate in fulfilling complementary roles, such as: architectural support, light absorption, energy transfer and electron transfer. All oxygenic organisms, ranging from cyanobacteria to algae and higher plants, contain photosystem I (PS I) and PS II reaction centres, with only minor variations in spite of their large taxonomic and ecological diversity. © 1987, Elsevier B.V.

Ono T, Zimmermann JL, Inoue Y, Rutherford AWet al., 1986, EPR evidence for a modified S-state transition in chloride-depleted Photosystem II, BBA - Bioenergetics, Vol: 851, Pages: 193-201, ISSN: 0005-2728

The role of chloride on the S-state transition in spinach Photosystem II (PS II) particles was investigated by EPR spectroscopy at low temperature and the following results were obtained. (1) After excitation by continuous light at 200 K, chloride-depleted particles did not show the EPR multiline signal associated with the S2 state, but only showed the broad signal at g = 4.1. The S2 multiline signal was completely restored upon chloride repletion. (2) In the absence of chloride the S2 multiline signal was not induced by a single flash excitation at 0°C. However, upon addition of chloride after the flash the signal was developed in darkness. (3) The amplitude of the multiline S2 signal thus developed upon chloride addition after flash illumination did not show oscillations dependent upon flash number. These results indicate that the O2-evolving complex in chloride-depleted PS II membranes is able to store at least one oxidizing equivalent, a modified S2 state, which does not give rise to the multiline signal. Addition of chloride converts this oxidizing equivalent to the normal S2 state which gives rise to the multiline signal. The modified S2 state is more stable than the normal S2 state, showing decay kinetics about 20-times slower than those of the normal S2 state, and the formation of higher S states is blocked. © 1986.
