Glutathione (GSH) is required for the oxidation of formaldehyde (HCHO) to formate catalyzed by formaldehyde dehydrogenase (FDH). The effects of GSH depletion on the mechanisms of labeling of macromolecules in the rat nasal mucosa and bone marrow by 3HCHO and H14CHO were investigated. Male rats were

Antagonistic reactions of arginine and lysine against formaldehyde and their relation to cell proliferation, apoptosis, folate cycle and photosynthesis.

1H, 13C NMR, ESMS and MS/MS investigations proved that there is an antagonism in the spontaneous reaction of formaldehyde with L-lysine and L-arginine. L-Arginine can only be hydroxymethylated on the guanidino group in a very fast reaction forming mono-, di-, and trihydroxymethyl arginines (HMA).

Labelling of chlorophylls and precursors by [2-14C]glycine and 2-[1-14C]oxoglutarate in Rhodopseudomonas spheroides and Zea mays. Resolution of the C5 and Shemin pathways of 5-aminolaevulinate biosynthesis by thin-layer radiochromatography.

The C-5 of 5-aminolaevulinate, a tetrapyrrole precursor which accumulates when inhibitory laevulinate is present, is derived from either the C-2 of glycine by the 5-aminolaevulinate-synthase-mediated Shemin pathway or the C-1 of 2-oxoglutarate by the C5 pathway. Thin-layer-radiochromatographic

The phytotoxicity of formaldehyde for spider plants (Chlorophytum comosum L.), tobacco plants (Nicotiana tabacum L. cv Bel B and Bel W3), and soybean (Glycine max L.) cell-suspension cultures was found to be low enough to allow metabolic studies. Spider plant shoots were exposed to 7.1 [mu]L L-1

Maize glutathione-dependent formaldehyde dehydrogenase cDNA: a novel plant gene of detoxification.

We have previously shown that intact plants and cultured plant cells can metabolize and detoxify formaldehyde through the action of a glutathione-dependent formaldehyde dehydrogenase (FDH), followed by C-1 metabolism of the initial metabolite (formic acid). The cloning and heterologous expression of

Free flavins have been extracted from shoots of etiolated corn (Zea mays L., var. Burpee Snowcross) and from yeast cells and separated from other substances by absorption on resorcinol-formaldehyde resin and talc columns and by thin layer chromatography. Riboflavin was the only free flavin present.
