l-Phenylalanine Ammonia-Lyase Activity During Germination of Phaseolus vulgaris.
l-Phenylalanine ammonia-lyase (PAL) activity develops in excised bean axes after approximately 5 hours of incubation and reaches a maximum level after 14 hours of incubation. Light does not affect the development of activity, but puromycin, cycloheximide, actinomycin D, and 5-fluorouracil inhibit.During this period of incubation both d- and l-p-fluorophenylalanine stimulate fresh weight increas...
متن کاملl-Phenylalanine Ammonia-lyase Activity in Robinia pseudoacacia Seedlings: I. Cyclic Phenomenon Activity during Continuous Light.
Influences of light and darkness on l-phenylalanine ammonia-lyase activity of black locust (Robinia pseudoacacia) seedlings were studied. Light initiates both an increase in enzyme activity (or enzyme synthesis) and a subsequent decrease in activity. These dual influences of light create cyclic changes in l-phenylalanine ammonia lyase activity in continuous light. The cyclic changes in activity...
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 کاملEthylene-induced Phenylalanine Ammonia-Lyase Activity in Carrot Roots.
Ethylene enhanced the activity of phenylalanine ammonialyase in carrot (Daucus carota L., var. "Nauty") root tissue. Slight increase in enzyme activity was exhibited by root discs incubated in ethylene-free air. It was probably due to the ethylene formed within the sliced tissue. Addition of ethylene to the air stream increased phenylalanine ammonia-lyase activity and the total protein content ...
متن کاملDetection of Phenylalanine Ammonia - Lyase Activity in Different Plant Parts of Anacardium Occidentale L
Phenylalanine ammonia-lyase (PAL) performs a major role in the biosynthesis of polyphenolic compounds, which are involved in the defense mechanism in harsh environments related to different stimuli. The present study was carried out to detect the activity of phenylalanine ammonia-lyase in different plant parts of Anacardium occidentale such as flower, young leaves, shoot tip, mature leaves, raw...
