Induction of phenylalanine ammonia lyase and pisatin by photosensitive psoralen compounds.
The psoralen compounds, xanthotoxin and 4,5', 8-trimethylpsoralen, when activated, increased phenylalanine ammonia lyase (PAL) activity and the synthesis of pisatin in excised pea pods. Pods presoaked 1 hr with 4,5',8-trimethylpsoralen and then irradiated 4 minutes with 366 nanometer ultraviolet light had twice as much PAL activity 3 hours after irradiation and 12 times as much PAL activity 20 ...
متن کاملYeast Phenylalanine Ammonia-lyase
I?henyialanine ammonia-lyase from the yeast Rhodotorula gluiinis was purified by salt fractionations and Sephadex chromatography. Density gradient centrifugation and Sephadex chromatography indicated its molecular weight to be about 275,000. Enzymatic deamination of several ring-substituted phenylalanine analogues and n-phenylalanine was studied. While cinnamic acid, a product of deamination, a...
متن کاملFungal and Plant Phenylalanine Ammonia-lyase
L-Phenylalanine is one of the essential amino acids that cannot be synthesized in mammals in adequate amounts to meet the requirements for protein synthesis. Fungi and plants are able to synthesize phenylalanine via the shikimic acid pathway. L-Phenylalanine, derived from the shikimic acid pathway, is used directly for protein synthesis in plants or metabolized through the phenylpropanoid pathw...
متن کاملEffects of Glyphosate on Metabolism of Phenolic Compounds I. Induction of Phenylalanine Ammonia-lyase Activity in Dark-grown Maize Roots
The herbicide glyphosate, N-(phosphonomethyl)glycine, induced phenylalanine ammonia-lyase (PAL) activity in the roots of dark-grown maize seedlings. This enzyme induction was shown to precede glyphosate-reduced fresh weight gain in the roots by 24--48 h. Feeding aromatic amino acids with glyphosate further inhibited growth while slightly lowering glyphosate-enhanced PAL activity. Soluble protei...
متن کاملInduction of phenylalanine ammonia-lyase in Xanthium leaf disks. Photosynthetic requirement and effect of daylength.
A cycloheximide-sensitive increase in the activity of phenylalanine ammonia-lyase (EC 4.3.1.5) occurs in Xanthium leaf disks exposed to light. Radioactive ammonia-lyase has been isolated by means of sucrose density gradient centrifugation and starch gel electrophoresis from disks fed l-isoleucine-U-(14)C or l-arginine-U-(14)C. The incorporation of radioactive amino acids into phenylalanine ammo...
