The Primary Reactions of Photosystems I and II of Algae and Higher Plants
, New Comprehensive Biochemistry, Vol: 15, Pages: 63-96, ISSN: 0167-7306This 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.

Uptake and processing of glycoproteins by rat hepatic mannose receptor
, American Journal of Physiology - Endocrinology and Metabolism, Vol: 252, ISSN: 0193-1849A linear compartmental model has been developed for the in vivo metabolism of glycoproteins. The model is applied to the interpretation of dynamic data from the rat on agalactoorosomucoid (AGOR), an N-acetylglucosamine (GlcNAc)-terminated glycoprotein, and three neoglycoproteins terminating in mannose [mannose36-bovine serum albumin (Man-BSA)] or glucose [maltose29-BSA (Mal29-BSA) and maltose8-BSA (Mal8-BSA)]. All of these proteins are taken up by the Man/GlcNAc receptor on hepatic sinusoidal cells. The rate of uptake was found to be determined by sugar type (Man-BSA, 0.78 min-1 > Mal29-BSA, 0.13 min-1), sugar density (Mal29-BSA > Mal8-BSA), and the geometry of the sugar display (AGOR, 0.51 min-1 > Mal29-BSA). Intracellular transport from the cell membrane to the lysosomes was slower for Man-BSA (~3 min) than for the other ligands (~0 min), suggesting that receptor-ligand uncoupling was slower for Man-BSA for which the receptor had the highest affinity or that extralysosomal catabolism of the other ligands occurred. Catabolism was also determined by the carbohydrate moiety of the ligand; it was greater for Mal29-BSA and Mal8-BSA (≥0.8 min-1) than for Man-BSA (0.27 min-1), and AGOR, with a complex oligosaccharide, was most resistant to degradation (0.14 min-1). An understanding of these structural features of glycoproteins that influence hepatic uptake, transport, and catabolism will be of value in drug targeting and for enzyme replacement in lysosomal storage disorders. Special emphasis is placed on model identifiability before experimentation as an aid in experiment design.

Are the biological effects of ethanol due to primary interactions with lipids or with proteins?
, Alcohol Alcohol Suppl, Vol: 1, Pages: 139-145, ISSN: 1358-6173The biological effects of ethanol and other simple organic molecules have traditionally been ascribed to their actions on the lipid portions of biological membranes. However, at the concentrations at which these molecules exert their pharmacological effects in man and other animals, changes in the structure and fluidity of lipid bilayers are extremely small and can be mimicked by a change in temperature of only about 1 degree C. On the other hand, we have found that the activity of a soluble protein can be markedly affected at these concentrations. Indeed, the concentrations of general anaesthetics which half-inhibit the activity of this enzyme are essentially identical to those which cause general anaesthesia in animals. The evidence thus suggests that ethanol and other simple molecules act directly on proteins rather than lipids.

EPR evidence for a modified S-state transition in chloride-depleted Photosystem II
, BBA - Bioenergetics, Vol: 851, Pages: 193-201, ISSN: 0005-2728The 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.
