RESUMEN
El Premio Nobel de Química de 2009 ha sido otorgado a VenkatramanRamakrishnan (MRC Laboratory of Molecular Biology, ReinoUnido), Thomas Steitz (Yale University, Estados Unidos) y Ada Yonath(Weizmann Institute of Science, Israel) por sus estudios sobre laestructura y función del ribosoma, la máquina macromolecular quelleva a cabo la síntesis de proteínas dentro de la célula. Los científicos,en un extraordinario esfuerzo de más de veinte años, aplicaron lacristalografía de rayos X para determinar la estructura atómica de esteenorme complejo macromolecular, de forma aislada y en asociacióncon los principales componentes que intervienen en el proceso de síntesisproteica. Los modelos resultantes han sido esenciales para entenderlos mecanismos que subyacen a dicho proceso, en particular cómoel ribosoma es capaz de descifrar el ARN de mensajero (que porta lainformación genética contenida en el ADN), cómo procede la catálisisdel enlace peptídico, y el modo en que varios antibióticos nos defiendende las infecciones bacterianas(AU)
ABSTRACT
Nobel Prize in Chemistry 2009 atomic structure of thecellular machinery for protein synthesisThe 2009 Nobel Prize in Chemistry has been awarded toVenkatraman Ramakrishnan (MRC Laboratory of Molecular Biology,United Kingdom), Thomas Steitz (Yale University, United States)and Ada Yonath (Weizmann Institute of Science, Israel) for theirstudies in the structure and function of the ribosome, a macromolecularmachine that carries out protein synthesis within the cell.The scientists, in an incredible tour de force that took over twentyyears, applied X-ray crystallography in order to determine the atomicstructure of this large macromolecular complex, alone and inassociation with the major components in the protein synthesisprocess. The resulting models have been essential to understand themechanisms underlying this process, in particular how the ribosomeis able to decode messenger RNA (which carries the geneticinformation stored in DNA), how peptide bond catalysis proceeds,and the way in which several antibiotics protect us from bacterialinfections(AU)
