Energy landscape of the ribosomal decoding center.

The ribosome decodes the genetic information that resides in nucleic acids. A key component of the decoding mechanism is a conformational switch in the decoding center of the small ribosomal subunit discovered in high-resolution X-ray crystallography studies. It is known that small subunit nucleotides A1492 and A1493 flip out of helix 44 upon transfer RNA (tRNA) binding; however, the operation principles of this switch remain unknown. Replica molecular dynamics simulations reveal a low free energy barrier between flipped-out and flipped-in states, consistent with a switch that can be controlled by shifting the equilibrium between states. The barrier determined by the simulations is sufficiently small for the binding of ligands, such as tRNAs or aminoglycoside antibiotics, to shift the equilibrium.

Common-pool resources and population genomics in Iceland, Estonia, and Tonga.

This paper addresses the application of the ethical concept of trust and the legal and political concept of public trust to population genomics projects in Iceland, Estonia, and Tonga. Focusing on trust and public trust, the paper explores analogies between the genomics projects and the treatment of other common-pool resources, making use of the notion of trust as an ethical demand, derived from the works of Emmanuel Levinas and Knud Eljer Løgstrup. The paper discusses the degree to which the ethical demands for trust and public trust have been established and maintained in the three national population genomics projects.

Structure of functionally activated small ribosomal subunit at 3.3 angstroms resolution.

The small ribosomal subunit performs the decoding of genetic information during translation. The structure of that from Thermus thermophilus shows that the decoding center, which positions mRNA and three tRNAs, is constructed entirely of RNA. The entrance to the mRNA channel will encircle the message when a latch-like contact closes and contributes to processivity and fidelity. Extended RNA helical elements that run longitudinally through the body transmit structural changes, correlating events at the particle's far end with the cycle of mRNA translocation at the decoding region. 96% of the nucleotides were traced and the main fold of all proteins was determined. The latter are either peripheral or appear to serve as linkers. Some may assist the directionality of translocation.

Privacy issues in second stage genomics.

Research that identifies genes useful in the prevention and treatment of disease will require access to biologic samples and medical records protected by traditional notions of privacy and confidentiality. Resolving conflicts between privacy and genomic research will require articulating the ethical rules that should govern such practices and then implementing those rules in the national, regional, or local health systems in which the data of interest exists. As consensus develops about the ethical rules that should govern such research, attention will shift to the practical and political problems of installing and implementing those rules in the agencies and institutions where such research will occur.
