Phenolic Compounds and Antioxidant Activity of Olea europaea L. Fruits and Leaves
Extracts of leaves, fruits and seeds of olive tree cultivars of Trás-os-Montes e Alto Douro (Portugal) were analysed by reverse phase HPLC with diode array detection and mass spectrometry (MS). ThisExpand
Enzymatic biotransformation of the azo dye Sudan Orange G with bacterial CotA-laccase.
In the present study we show that recombinant bacterial CotA-laccase from Bacillus subtilis is able to decolourise, at alkaline pH and in the absence of redox mediators, a variety of structurallyExpand
Insulin glycation by methylglyoxal results in native-like aggregation and inhibition of fibril formation
It is proposed that higher dynamics in glycated insulin could prevent the formation of the rigid cross-β core structure found in amyloid fibrils, thereby contributing to the reduction in the ability to form fibril formation and to the population of different aggregation pathways like theformation of native-like aggregates.

Xbp1-independent Ire1 signaling is required for photoreceptor differentiation and rhabdomere morphogenesis in Drosophila.
The results show that the role of Ire1 during photoreceptor differentiation is independent of Xbp1 function and demonstrate the physiological relevance of the RIDD mechanism in this specific paradigm. Expand
Desulfoferrodoxin structure determined by MAD phasing and refinement to 1.9-Å resolution reveals a unique combination of a tetrahedral FeS4 centre with a square pyramidal FeSN4 centre
Abstract The structure of desulfoferrodoxin (DFX), a protein containing two mononuclear non-heme iron centres, has been solved by the MAD method using phases determined at 2.8 Å resolution. The ironExpand
Tick-borne diseases in cattle: applications of proteomics to develop new generation vaccines.
An overview of the so called "Omics" studies currently available on these tick-borne pathogens, giving emphasis to proteomics and how it may help to discover new vaccine candidates to control TBDs is presented. Expand
Analysis of phenolic compounds in Muscatel wines produced in Portugal
A liquid chromatography method associated with mass spectrometry and diode array, fluorescence and electrochemical detectors was used in order to study phenolic composition of Muscatel sweet winesExpand
Hydrogenases in Desulfovibrio vulgaris Hildenborough: structural and physiologic characterisation of the membrane-bound [NiFeSe] hydrogenase
Evidence was obtained that the [NiFeSe] Hase is post-translationally modified to include a hydrophobic group bound to the N-terminal, which is responsible for its membrane association, and several conserved residues close to the redox centres were identified, which may be relevant to the higher activity displayed by [Ni Fe Se] Hases.

Characterisation of Zea mays L. plastidial transglutaminase: interactions with thylakoid membrane proteins.
The characterisation and demonstration of the association with photosystem II (PSII) protein complexes indicated that maize chlTGase forms part of a specific PSII protein complex, which includes LHCII, ATPase and pSbS proteins, and the results are discussed in relation to the interaction between these proteins.

The Effect of Tannins on Mediterranean Ruminant Ingestive Behavior: The Role of the Oral Cavity
The effects of dietary tannins on feeding behavior, and the role of the oral cavity in this process, are detailed, with focus on domestic ruminant species. Expand
