(a.) Pertaining to, or derived from, fumitory (Fumaria officinalis).
Example Sentences:
(1) Malonate, at a concentration that was not totally growth-inhibitory (1mM) prevented the inhibition of acetate-stimulated isocitrate lyase synthesis by succinate, but fumarate still inhibited in the presence of malonate.
(2) Insertion of the fusion-generating phage Mud1 (Ap, lacZ) yielded two similar isolates, DC511 and DC512, which were unable to grow aerobically on acetate or alpha-ketoglutarate but which could use succinate, malate, fumarate, glycerol, and various sugars.
(3) Expression of galactokinase from the frd promoter-galK operon fusion plasmid was repressed by oxygen and by nitrate and was induced by fumarate, indicating that frd gene expression is regulated at the transcriptional level by these terminal electron acceptors.
(4) Glucose appears to be an adequate substrate for stria in vitro since glutamate, pyruvate, and fumarate did not increase the respiratory rate.
(5) Uptake of fumarate and malate, which share the succinate-transport system, is also accompanied by the uptake of approximately two protons per molecule of fumarate or malate.
(6) Pigs weaned at 21 d of age (n = 72) were fed a 20% CP corn-soybean meal-based diet (control) with 1.5% fumaric or 1.5% citric acid added to observe the effect of these acids on the pH, chloride ion concentration (Cl-), VFA profile, and microflora population in the stomach, jejunum, cecum, and lower colon contents at -2, 0, 3, 7, 14, and 21 d postweaning.
(7) One ATP is produced for each pair of electrons transferred to fumarate.
(8) Mutants lacking the membrane-associated Mg2+-dependent adenosine triphosphatase cannot grow anaerobically on glycerol with fumarate as the hydrogen acceptor, although they can grow aerobically on glycerol alone.
(9) This strain lacked a chromosomal frd operon and was unable to grow anaerobically on glycerol and fumarate.
(10) A b-type cytochrome, possibly a c-type cytochrome, and a very active fumarate reductase were present in the cells.
(11) In these models, a 1-week treatment period with repirinast, like other oral antiallergic asthma medications (e.g., ketotifen, fumarate), provides no protection against airway responses to methacholine or allergen.
(12) The induction of fumarate-dependent electron transport in B. fragilis is associated with some aminoglycoside transport that is of poor efficiency relative to bacteria with electron transport to oxygen or nitrate.
(13) This oxidation in cells grown anaerobically in a glucose minimal medium is linked via menaquinone to the fumarate reductase enzyme coded for by the frd gene and is independent of the cytochromes.
(14) Uptake rates of 0.1 mM citrate and alpha-ketoglutarate were inhibited by greater than 90% by 10 mM succinate, malate, fumarate, or oxaloacetate, indicating the presence in the brush border membrane of a transport system highly specialized for the renal conservation of intermediates of the tricarboxylic acid cycle.
(15) FrdC was found to be homologous with the cytochrome b (SdhC) of the Bacillus subtilis succinate dehydrogenase, but not with the hydrophobic subunits of the fumarate reductase or succinate dehydrogenase of Escherichia coli.
(16) The specific activity of pyruvate-ferredoxin oxidoreductase, malate dehydrogenase, fumarate reductase, and transcarboxylase varied significantly in cells grown on different energy sources.
(17) Fumarate hydratase activity also decreased but alcohol dehydrogenase and the sum of the succinate dehydrogenase and fumarate reductase activities increased when residual O2 was removed from the sparging gas.
(18) Membrane vesicles isolated from Bacillus subtilis W23 catalyze active transport of the C4 dicarboxylic acids L-malate, fumarate, and succinate under aerobic conditions in the presence of the electron donor reduced beta-nicotinamide adenine dinucleotide or the non-physiological electron donor system ascorbate-phenazine methosulfate.
(19) The coupling enzymes, fumarase (fumarate to L-malate) and malic enzyme (L-malate to pyruvate and NADPH), are adsorbed to nitrocellulose prior to blotting.
(20) The Michaelis constant (Km) and maximum velocities (Vmax) for fumarate reduction and succinate oxidation by the tissue homogenates from the three species were determined.
Fumitory
Definition:
(n.) The common uame of several species of the genus Fumaria, annual herbs of the Old World, with finely dissected leaves and small flowers in dense racemes or spikes. F. officinalis is a common species, and was formerly used as an antiscorbutic.
Example Sentences:
(1) Major results of these studies are presented for the following plants: Garlic, Geranium; Hellebore; Mistletoe; Olive; Valerian; Hawthorn; Pseucedanum arenarium; Periwinkle; Fumitory.
