Resumen
[ES]La proteína K-RAS pertenece a un grupo de proteínas pequeñas de unión a GTP, conocida como la superfamilia de RAS o GTPasas de tipo RAS. Ésta, consta de 188 aminoácidos con una masa molecular de 21,6 kDa y participa en la transducción de señal intracelular. Esta proteína permanece inactiva hasta que se une a GTP, unión que provoca un cambio en la conformación de la proteína, activándola y de este modo amplificando la actividad GTPasa de la proteína 100.000 veces, aumentando así la proliferación celular de las células cancerosas. En este trabajo se ha realizado el estudio teórico de tres posibles cabezas de serie para la desactivación de la proteína K-RAS mediante simulaciones computacionales de dinámica molecular. Para ello se utiliza la suite de AMBER, que consta de un conjunto de programas para aplicar el campo de fuerza AMBER a biomoléculas, en nuestro caso.
[EN]The K-RAS protein belongs to a group of small GTP-binding proteins, known as the RAS superfamily or GTPases RAS-like. It is built by 188 amino acids with a molecular mass of 21.6 kDa and it is involved in intracellular signal transduction. This protein remains inactive until it binds to GTP, binding which causes a change in the conformation of the protein, activating it and thus amplifying GTPase activity of the protein 100,000 times, increasing cell proliferation of cancer cells. This work was carried out the theoretical study of three possible leads for the deactivation of the K-RAS protein by molecular dynamics computer simulations. For this purpose, the AMBER suite, which consists of a set of programs to implement the AMBER force field to biomolecules, in our case, is used.
