Regulation of C4 -phosphoenolpyruvate carboxylase activity by ambient CO2
Light activation of phosphoenolpyruvate carboxylase from the leaves of the C4 plant Setaria verticillata (L.) is more pronounced at low CO2 levels. The 2-fold activation observed at physiological ambient CO2 becomes 3.64-fold ...
Mg2+-Regulation of C4 and CAM Adenylate Kinase
The rate of adenylate kinase activity from the C4 plant Saccharum ravenae at saturating substrate and Mg2+ concentrations is 7 times higher in the direction of ADP formation (AMP + ATP →2ADP) than in the reverse direction. ...
Levels of Adenylate Kinase in CAM Plants of Different Decarboxylation Pathway
Adenylate kinase activities in «malic enzyme» CAM plants are 4–20 times higher than those of the «PEP carboxykinase» CAM plants. The activities in the first group are more than enough to sustain the required rates of AMP ...
A Covalently Constrained Congener of the Saccharomyces cerevisiae Tridecapeptide Mating Pheromone Is an Agonist
(The American Society for Biochemistry and Molecular Biology, Inc., 1989)
An analog of a-factor, the Saccharomyces cerevisiae tridecapeptide mating pheromone (Trp-His-Trp-LeuGln-Leu-Lys-Pro-Gly-Gln-Pro-Met-Tyr), in which the side chains of Lys7 and Gln" were covalently linked, was synthesized ...
Lethal effect of methyl and propyl parabens as related to Staphylococcus aureus lipid composition
The relationship between staphylococcal lipid composition and resistance to parabens was investigated. Chloroform-methanol extractable lipids were determined gravimetrically. Phospholipid and fatty acid fractions were ...
Effect of selected phenolic compounds on the membrane-bound adenosine triphosphatase of Staphylococcus aureus
(Elsevier B. V., 1987-07)
The effect of selected phenolic compounds on the membrane-bound ATPase activity of two strains of Staphylococcus aureus was studied. These phenolic compounds were: butylated hydroxyanisole (BHA), butylated hydroxytoluene ...
