On the occurrence of thioredoxin in Trypanosoma cruzi
(Elsevier Science, 2006-02)
The full coding sequence for thioredoxin from Trypanosoma cruzi (TcTRX) strain Tulahuen O has been cloned into the pRSETA vector. The protein was expressed in Escherichia coli with an N-terminal extension of six histidine ...
FixL-like sensor FlbS of Brucella abortus binds haem and is necessary for survival within eukaryotic cells
(Elsevier Science, 2013-08-14)
Replication of Brucella inside eukaryotic cells is essential for pathogenesis, and successful infection requires rapid adaptation to the intracellular milieu. Close relatives of Brucella use the two-component system FixLJ ...
Mapping the protein-binding sites for iridium(III)-based CO-releasing molecules
(Royal Society of Chemistry, 2016-06)
A combination of mass spectrometry, Raman microspectroscopy, circular dichroism and X-ray crystallography has been used to obtain detailed information on the reaction of an iridium-based CO-releasing molecule (Ir-CORM), ...
Las versátiles proteínas zinc fingers
(Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales. Departamento de Química Biológica, 2006-12)
Los dominios zinc fingers son elementos estructurales muy estables cuya particularidad es la coordinación de uno o más átomos de zinc a través de residuos de cisteínas e histidinas. Los zinc fingers son uno de los motivos ...
Prevention of in vitro oxidation of low density lipoproteins (LDL) by amaranth peptides released by gastrointestinal digestion
(Elsevier, 2017-07)
The objective of this work was to analyze the capacity of amaranth peptides generated by gastrointestinal digestion to prevent LDL oxidation. A simulated gastrointestinal digest from protein isolate (Id); Id fractions ...
Evidence for a histaminergic system in the human testis
(Elsevier Science Inc, 2005-12)
The complete lack of information about mast cells as a source of histamine and potential target cells for histamine in human testes prompted us to investigate these issues in testes of fertile and infertile patients using ...
Zn finger containing proteins as targets for the control of viral infections
(Bentham Science Publishers, 2007-09)
The zinc finger proteins have fascinated many research groups because of their modular assembly, broad range of biological functions and more recently because they are attractive targets for antiviral therapy. The zinc ...
Native CuA Redox Sites are Largely Resilient to pH Variations within Physiological Range
(Royal Society of Chemistry, 2013-06)
Previous studies on engineered CuA centres have shown that one of the histidine ligands is protonated and dissociated from the metal site at physiological pH values, thus suggesting a role in regulating proton-coupled ...
Impact of copper ligand mutations on a cupredoxin with a green copper center
(Elsevier Science, 2017-05)
Mononuclear cupredoxins contain a type 1 copper center with a trigonal or tetragonal geometry usually maintained by four ligands, a cystein, two histidines and a methionine. The recent discovery of new members of this ...
Fouling behaviour of polyethersulfone UF membranes made with different PVP
(Elsevier Science, 2003-01-01)
Several polyethersulfone (PES) ultrafiltration membranes have been made with small quantities of polyvinyl-pyrrolidone (PVP) of different molecular weights to increase the permeability without a significant reduction in ...
