Five phenylethanoid glycosides (acteoside, isoacteoside, beta-oxoacteoside, beta-hydroxyacteoside, and salidroside) were isolated from a cell suspension culture of Olea europaea. We examined the biosynthesis of acteoside in olive cell cultures by using feeding experiments with stable isotope labeled
Parkinson's disease (PD) is an age-related disease in which dopaminergic neurons in the nigrostriatal pathway are destroyed, resulting in movement and behavioral problems. Oxidative stress and the generation of reactive oxygen species play key roles in neurodegenerative diseases, such as PD.
An olive (Olea europaea L.) β-glucosidase was purified to apparent homogeneity by salting out with ammonium sulfate and using specifically designed sepharose-4B-L-tyrosine-1-napthylamine hydrophobic interaction chromatography. The purification was 155 fold with an overall enzyme yield of 54%. The
An allergen has been isolated from a saline extract of olive tree (Olea europaea) pollen. The protein consists of a single polypeptide chain of 9.2-kDa, as determined by mass spectrometry. It contains neither tryptophan nor tyrosine residues, and displays an acidic isoelectric point. The secondary
The oxidative decarboxylation of L-tryptophan to yield 3-indoleacetamide, catalyzed by tryptophan 2-monooxygenase, represents a controlling reaction in the synthesis of indoleacetic acid by Pseudomonas savastanoi (Pseudomonas syringae pv. savastanoi), a gall-forming pathogen of olive (Olea europea
The olive tree (Olea europaea L.) is the most important oil-producing crop of the Mediterranean basin. However, although plant protection measures are regularly applied, disease outbreaks represent an obstacle towards the further development of the sector. Therefore, there is an urge for the
