Cclxxiv. Studies on Carotenoids.' Iii. an Isomeride of Lutein Isolated from the Furze (ulex Europaeus)
WE have isolated from the yellow flowers of the furze a new carotenoid which in its properties is very similar to lutein. It crystallizes from absolute methyl alcohol in stellate groups of pale yellow twinned prisms. The crystals are dichroic and have a strong birefringence. Like lutein this yellow form, which does not contain methyl alcohol of crystallization, changes in contact with the solve...
متن کاملUlex europaeus agglutinin II (UEA-II) is a novel, potent inhibitor of complement activation.
Complement is an important mediator of vascular injury following oxidative stress. We recently demonstrated that complement activation following endothelial oxidative stress is mediated by mannose-binding lectin (MBL) and activation of the lectin complement pathway. Here, we investigated whether nine plant lectins which have a binding profile similar to that of MBL competitively inhibit MBL dep...
متن کاملThe 2.2 A resolution structure of the O(H) blood-group-specific lectin I from Ulex europaeus.
The tertiary and quaternary structure of the lectin I from Ulex europaeus (UE-I) has been determined to 2.2 A resolution. UE-I is a dimeric metalloglycoprotein that binds the H-type 2 human blood group determinant [alpha-L-Fucalpha(1-->2)-beta-D-Galbeta(1-->4)-beta-D-Glc NAcalpha-]. Nine changes from the published amino acid sequence were necessary to account for the electron density. The quate...
متن کاملAccumulation of smooth cisternae in the tapetal cells of Ulex europaeus L. (Papilionoideae).
In addition to the events occurring in the tapetal cells of most angiosperm species (cell wall lysis, endoplasmic reticulum development and sporopollenin deposition on the outer face of the cells) the tapetum of Ulex europaeus L. exhibits two characteristics. No orbicules, generally associated with the locular face of the secretory tapetum of angiosperms, are found, but some intracellular macro...
متن کاملInvasive Plants and Enemy Release: Evolution of Trait Means and Trait Correlations in Ulex europaeus
Several hypotheses that attempt to explain invasive processes are based on the fact that plants have been introduced without their natural enemies. Among them, the EICA (Evolution of Increased Competitive Ability) hypothesis is the most influential. It states that, due to enemy release, exotic plants evolve a shift in resource allocation from defence to reproduction or growth. In the native ran...
