Functional properties of a phenylalanine ammonia-lyase promoter from Arabidopsis.
Phenylalanine ammonia-lyase (PAL) is encoded by a small family of genes in Arabidopsis. We cloned and partially characterized one of these genes, PAL1. The deduced amino acid sequence is highly similar to PAL from bean, parsley, and rice. The promoter contains sequence elements homologous to two putative regulatory elements conserved among several phenylpropanoid genes. The regulation of the PA...
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 کاملl-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 کاملincreased podophyllotoxin production and phenylalanine ammonia lyase activity in cell culture of linum album by methyl jasmonate
linum album l. is containing pharmaceutical composition podophyllotoxin(ptox) which is currently being used as a precursor to semi-synthetic anticancer drugs etoposide, teniposide and etopophos. cell culture is as an important source for the production of ptox. several strategies, including treatment with elicitors have shown for enhanced production of secondary metabolites in cell culture syst...
