Low-Resolution Molecular Models Reveal the Oligomeric State of the PPAR and the Conformational Organization of Its Domains in Solution
(PUBLIC LIBRARY SCIENCESAN FRANCISCO, 2012)
The peroxisome proliferator-activated receptors (PPARs) regulate genes involved in lipid and carbohydrate metabolism, and are targets of drugs approved for human use. Whereas the crystallographic structure of the complex ...
Carbon stable isotopes as indicators of the origin and evolution of CO2 and CH4 in urban solid waste disposal sites and nearby areas
(Springer, 2016-02)
Isotopic compositions of CH4 and CO2 surface and subsurface gases and groundwater from an urban solid waste disposal site from Gualeguaychú city (Argentina) were measured to detect origin, depth distribution, migration ...
Acidity evolution on highly dispersed chromium supported on mesostructured silica: The effect of hydrothermal treatment and calcination temperature
(Elsevier Science, 2020-03-01)
Mesoporous Cr-MCM-41 catalysts were synthesized, under different hydrothermal temperatures, by the sol-gel procedure using tetraethylorthosilicate (TEOS) as silica precursor and cetyltrimethylammonium bromide (CTAB) as a ...
Heat Shock Protein 90 kDa (Hsp90) Has a Second Functional Interaction Site with the Mitochondrial Import Receptor Tom70
(Amer Soc Biochemistry Molecular Biology Inc, 2016-09-02)
To accomplish its crucial role, mitochondria require proteins that are produced in the cytosol, delivered by cytosolic Hsp90, and translocated to its interior by the translocase outer membrane (TOM) complex. Hsp90 is a ...
The Specific Elongation Factor to Selenocysteine Incorporation in Escherichia coli: Unique tRNASec Recognition and its Interactions
(2021-11-19)
Several molecular mechanisms are involved in the genetic code interpretation during translation, as codon degeneration for the incorporation of rare amino acids. One mechanism that stands out is selenocysteine (Sec), which ...
Real-time reaction monitoring by probe electrospray ionization mass spectrometry
(John Wiley & Sons Ltd, 2010-06)
Probe electrospray ionization (PESI) is a modified version of the electrospray ionization (ESI), where the capillary for sampling and spraying is replaced by a solid needle. High tolerance to salts and direct ambient ...
Specific isotope labeling of transthyretin for nuclear magnetic resonance and mass spectrometry studies — Marcaje isotópico específico de transtiretina para estudios en resonancia magnética nuclear y espectrometría de masas
(Universidad de Chile, 2010)
Las proteínas son moléculas versátiles que juegan una variedad de roles en la mantención del cuerpo humano, tal como el transporte de nutrientes. La transtiretina (TTR) es una proteína homotetramérica de 55 kDa que se ...
