Informed consent: A study of patients with life-threatening illnesses.

Background: The relationship between healthcare professionals and patients in the Spanish health sector has undergone dramatic change. One aspect of this is that the use of informed consent has become a key factor in the delivery of adequate healthcare. But although a certain period of time has already passed since informed consent started to be used, in Spain there is still doubt about how adequately informed consent is being used.

Structure and interaction with phospholipids of a prokaryotic lipoxygenase from Pseudomonas aeruginosa.

Lipoxygenases (LOXs), which are essential in eukaryotes, have no confirmed function in prokaryotes that are devoid of polyunsaturated fatty acids. The structure of a secretable LOX from Pseudomonas aeruginosa (Pa_LOX), the first available from a prokaryote, presents significant differences with respect to eukaryotic LOXs, including a cluster of helices acting as a lid to the active center. The mobility of the lid and the structural variability of the N-terminal region of Pa_LOX was confirmed by comparing 2 crystal forms.

Bacterial lipoxygenases, a new subfamily of enzymes? A phylogenetic approach.

Lipoxygenases (EC. 1.13.

Functional characterization of ExFadLO, an outer membrane protein required for exporting oxygenated long-chain fatty acids in Pseudomonas aeruginosa.

Bacterial proteins of the FadL family have frequently been associated to the uptake of exogenous hydrophobic substrates. However, their outer membrane location and involvement in substrate uptake have been inferred mainly from sequence similarity to Escherichia coli FadL, the first well-characterized outer membrane transporters of Long-Chain Fatty Acids (LCFAs) in bacteria. Here we report the functional characterization of a Pseudomonas aeruginosa outer membrane protein (ORF PA1288) showing similarities to the members of the FadL family, for which we propose the name ExFadLO.

Precursor uptake assays and metabolic analyses in isolated tomato fruit chromoplasts.

Background: Carotenoids are the most widespread group of pigments found in nature. In addition to their role in the physiology of the plant, carotenoids also have nutritional relevance as their incorporation in the human diet provides health benefits. In non-photosynthetic tissues, carotenoids are synthesized and stored in specialized plastids called chromoplasts.

Cloning and expression of a lipoxygenase from Pseudomonas aeruginosa 42A2.

In order to produce (S) 10-monohydroxy-8E-octadecenoic acid (MHOD) from oleic acid, a full-length probable lipoxygenase cDNA from Pseudomonas aeruginosa 42A2 was cloned and expressed in Escherichia coli BL21(DE3). The recombinant protein was purified by affinity chromatography to electrophoretic homogeneity and specifically stained. Its molecular mass was 70 kDa.
