Structural basis for selective recognition of acyl chains by the membrane-associated acyltransferase PatA
(Nature Publishing, 2016-03)
The biosynthesis of phospholipids and glycolipids are critical pathways for virtually all cell membranes. PatA is an essential membrane associated acyltransferase involved in the biosynthesis of mycobacterial phosphatidy ...
Metabolic alterations in prostate cancer pathogenesis
(2016-09-16)
Activation of the PTEN-PI3K-mTORC1 pathway consolidates metabolic programs thatsustain cell growth, proliferation and promote cancer initiation and progression. In this thesis workwe describe a novel molecular mechanism ...
Physical principles underlying structure, mechanics and dynamic re-organization of hyaluronan-rich matrices - from tissues to supramolecular models in experiment and theory
(2016-07-29)
The goal of this research project is to understand the physical principles that underlie the structure, mechanics and dynamic reorganization of hyaluronan-rich pericellular and extracellular matrices. Many cells produce a ...
Soils under long-term aided phytostabilization are a reservoir for transmissible antibiotic resistance plasmids.
(2016-06-28)
En la actualidad, cada vez son más habituales los brotes infecciosos donde la mayoría de los antibióticos se muestran ineficaces debido a un creciente número de patógenos resistentes a los mismos. Incluso algunos de los ...
Computational and biophysical methods in characterization of protein-protein and protein-ligand interactions
(2016-02-02)
Todas las moléculas - tan simples como la molécula de hidrógeno o tan extremadamente complejas como una proteína - resultan de la unión de átomos individuales. Los átomos están unidos mediante fuerzas intramoleculares ...
Implication of ceramide 1-phosphate in obesity-associated processes. Role of PEMT
(2016-01-22)
Obesity is the most common metabolic disease in developed nations and has become a global epidemic in recent years. Therefore, understanding the molecular mechanisms that regulate obesity-associated processes, such as cell ...
Mechanisms of MPER helix binding at membrane interfaces and implications for the broad neutralization of HIV by antibodies
(2016-12-16)
En esta tesis se lleva a cabo un estudio detallado de la función que desempeña el lazo CDR-H3 de losanticuerpos anti MPER 4E10 y 10E8 en al unión y neutralización del VIH así como la contribución de launión directa a lípidos ...
Functional organization of the HIV lipid envelope
(Nature, 2016-09-28)
The chemical composition of the human immunodeficiency virus type 1 (HIV-1) membrane is critical for fusion and entry into target cells, suggesting that preservation of a functional lipid bilayer organization may be required ...
Structural changes induced by acidic pH in human apolipoprotein B-100
(Nature Research, 2016-11-08)
Acidification in the endosome causes lipoprotein release by promoting a conformational change in the LDLR allowing its recycling and degradation of LDL. Notwithstanding conformational changes occurring in the LDLR have ...
