Characterization of an L-Ascorbate Catabolic Pathway with Unprecedented Enzymatic Transformations
, 2019 L-Ascorbate (vitamin C) is ubiquitous in both our diet and the environment. Ralstonia eutropha H16 (Cupriavidus necator ATCC 17699) uses L-ascorbate as sole carbon source but lacks the genes encoding the known catabolic pathways.

The Trypanosoma cruzi vitamin C dependent peroxidase confers protection against oxidative stress but is not a determinant of virulence. [PDF]
, 2015 BACKGROUND: The neglected parasitic infection Chagas disease is rapidly becoming a globalised public health issue due to migration. There are only two anti-parasitic drugs available to treat this disease, benznidazole and nifurtimox. Thus it is important

Increasing ascorbate levels in crops to enhance human nutrition and plant abiotic stress tolerance
, 2017 Ascorbate (or vitamin C) is an essential human micronutrient predominantly obtained from plants. In addition to preventing scurvy, it is now known to have broader roles in human health, for example as a cofactor for enzymes involved in epigenetic ...

Ascorbate function and associated transport systems
, 2000 : Ascorbate is present in different cell compartments of higher plant cells. At a physiological level, the best-studied phenomena involving ascorbate is its participation in an oxygen scavenging pathway in the chloroplast known as the ascorbate ...

, 2016 Despite recent evidence for an anti-tumour role for high-dose ascorbate, potential mechanisms of action are still unclear. At mM concentrations that are achieved with high-dose intravenous administration, autoxidation of ascorbate can generate cytotoxic ...

Control of ascorbate synthesis by respiration and its implications for stress responses [PDF]
, 2003 We show for the first time that respiration can control ascorbate (AA) synthesis in plants. Evidence for this control is provided by (a) the localization of L-galactono-1,4-lactone dehydrogenase (GalLDH), the terminal enzyme in AA biosynthesis, with ...

Journal of the agricultural chemical society of Japan, 1938 5mgのAscorbin酸の37±1°に於ける自己酸化に對しVitamin A原液(100,000 I.U.)を0.0～0.2cc作用せしむる時0.0～0.0005ccまでは自己酸化抑制作用は發現せず, 0.001ccに於いて漸く發現し而して0.12ccまではVitamin Aの作用量と共に抑制作用は増大し0.12ccに於いて最大點に達し0.14cc以上に於いては抑制作用は消滅し酸化促進作用と化し而も此の作用は量比的である.但し本實驗に於てはVitamin AのAceton溶液を用ゐたから實驗値に對して幾分の誤差はまぬかれないであらう.

Ascorbate-Deficient vtc2 Mutants in Arabidopsis Do Not Exhibit Decreased Growth
, 2016 In higher plants the L-galactose pathway represents the major route for ascorbate biosynthesis. The first committed step of this pathway is catalyzed by the enzyme GDP-L-galactose phosphorylase and is encoded by two paralogs in Arabidopsis – VITAMIN C2 ...

, 2001 Erythrocytes can reduce extracellular ascorbate free radicals by a plasma membrane redox system using intracellular ascorbate as an electron donor. In order to test whether the redox system has electrogenic properties, we studied the effect of ascorbate ...
