Rubisco: attempts to reform a promiscuous enzyme,se/oxygenase (Rubisco; EC 4.1.1.39) is an inefficient enzyme; it has a low turnover number and catalyses several competing reactions, including oxygenation of ribulose-1,5-bisphosphate (ribulose-P.), in addition to the carboxylation of ribulose-P..

Integration of metabolism within non-photosynthetic plastids, and with the cytosol,ust cross the plastid envelope. This review considers our current knowledge of which intermediates may be transported, the potential for competition for substrates between intraplastidic pathways, and the integration of biosynthetic with oxidative metabolism within the organelle. There is considerab

Compartmentation of metabolites between the subcellular compartments of leaves, the apoplast, the phloroplastic and vacuolar fraction of leaves. In barley, potato, spinach and tobacco the concentrations of amino acids and sucrose are very high in the cytosol, but low in the vacuole. In contrast, hexoses are almost exclusively located in the vacuole in these species. The concentration of metabolit

Regulation of starch synthesis in storage organs,amylose and amylopectin, that make up the starch granule..The organisation of amylopectin molecules to form the matrix of the granule is made possible by the fact that the polymer has a polymodal distribution of branch lengths. It has been suggested that this distribution is brought about through th

The integration of sucrose and fructan metabolism in temperate grasses and cereals,ew concentrates upon the characterisation of novel elements of fructan metabolism. Fructan structures are shown to be both varied and complex, but to possess a consistency within species which argues for a biosynthetic mechanism with a high degree of specificity. The synthetic and degradative mechan
