Enzymic reactions in mammalian metabolism of y-hydroxyglutamic acid

Glyoxylic acid has recently been shown to be formed from 7-hydroxyglutamate by an enzyme system present in rat-liver extracts z. Paper-chromatographic identification of alanine as one other product of this process suggested the possibilities of either a direct cleavage of the substrate or a series of reactions with formation of alanine as a terminal product. The present experiments show that th...

Ascorbic Acid and Ascorbic Acid Oxidizing Enzymes of Green Bean Plants Deficient in Manganese.

Recently in this laboratory (1) soybeans grown on manganese-deficient field plots were analyzed for ascorbic acid and ascorbic acid-oxidizing enzymes. Contrary to some reports in the literature, no consistent relationship was found between manganese deficiency symptoms and ascorbic acid or the enzymes which oxidize it. The present study was performed with solution cultures to provide a more rig...

Homocysteine Biosynthesis in Green Plants

Optimal conditions for biosynthesis of cystathionine with crude extracts of green plants were determined. The specific activities observed under these conditions are considerably higher than those initially detected (GIOVANELLI, J., AND MUDD, S. H. (1966) Biochem. Biophys. Res. Commun. 25, 366), and compare favorably with those of bacterial extracts. At near saturating concentrations of homoser...

Light Production by Green Plants

1. Green plants have been found to emit light of approximately the same color as their fluorescent light for several minutes following illumination. This light is about 10(-3) the intensity of the fluorescent light, about one-tenth second after illumination below saturation or 10(-6) of the intensity of the absorbed light. 2. The decay curve follows bimolecular kinetics at 6.5 degrees C. and re...
