Étude préparatoire a une reconquête des niveaux de ressource en langouste royale (Palinurus elephas) en mer d'Iroise
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Latrouite, Daniel; Lazure, Pascal.
The study conducted in the framework of an agreement between Ifremer and the Local fisheries committee at Audierne is part of a project to restore spiny lobster Palinurus elephas stock levels in the Iroise Sea. It is supported by professional fishermen from Finistère and by the Regional fisheries committee of Brittany.  After a brief review of the way lobster stocks are managed worldwide, followed by the major biological and ecological features of red lobster and the state of fisheries in Europe and North Africa, the very poor state of the resource along French coast is borne out by the statistics of landings.   Various scenarios (not alternatives) to promote the rebuilding of the biomass are suggested:  minimum landing size increase, seasonal closure of...

Important amino acid residues of potato plant uncoupling protein (StUCP)
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Jezek,P.; Costa,A.D.T.; Vercesi,A.E.
Chemical modifications were used to identify some of the functionally important amino acid residues of the potato plant uncoupling protein (StUCP). The proton-dependent swelling of potato mitochondria in K+-acetate in the presence of linoleic acid and valinomycin was inhibited by mersalyl (Ki = 5 µM) and other hydrophilic SH reagents such as Thiolyte MB, iodoacetate and 5,5'-dithio-bis-(2-nitrobenzoate), but not by hydrophobic N-ethylmaleimide. This pattern of inhibition by SH reagents was similar to that of brown adipose tissue uncoupling protein (UCP1). As with UCP1, the arginine reagent 2,3-butadione, but not N-ethylmaleimide or other hydrophobic SH reagents, prevented the inhibition of StUCP-mediated transport by ATP in isolated potato mitochondria or...

Membrane proteins: functional and structural studies using reconstituted proteoliposomes and 2-D crystals
Provedor de dados: Brazilian Journal of Medical and Biological Research
Autores: Rigaud,J.-L.
Reconstitution of membrane proteins into lipid bilayers is a powerful tool to analyze functional as well as structural areas of membrane protein research. First, the proper incorporation of a purified membrane protein into closed lipid vesicles, to produce proteoliposomes, allows the investigation of transport and/or catalytic properties of any membrane protein without interference by other membrane components. Second, the incorporation of a large amount of membrane proteins into lipid bilayers to grow crystals confined to two dimensions has recently opened a new way to solve their structure at high resolution using electron crystallography. However, reconstitution of membrane proteins into functional proteoliposomes or 2-D crystallization has been an...
