New targets for antibiotics: self assembling ribonucleoprotein complexes

核糖体是一种分子机器，它执行一项基本的生物学任务

Ribosomes are molecular machines that carry out an essential biological task: they synthesize proteins. Thus, bacterial ribosomes are logical targets for antibiotics. However, the emergence (and growth of) drug resistant bacteria poses a major threat to human health. New strategies for attacking resistant strains must be developed. Recent, breakthrough structural studies of the ribosome enable an entirely new approach to interfering with the ribosome: preventing its self assembly. Here, we propose to develop and apply a new experimental method for measuring structural changes accompanying the real time self-assembly of the ribosome or its subunits. If successful, this approach will enable identification of folding pathways or partially folded states that may be amenable to attack.
