Yavuz and Ali Coskun | | | Porous materials are well studied for gas capture and separation technologies. Here, the authors report nitrogen-rich, nanoporous polymers, which display very high CO2/N2 selectivity with increasing temperature, which may be attributable to an entropically driven N2-phobicity effect. | | | 15 Jan | Nat Commun 4:1357 doi:10.1038/ncomms2359 (2013) | | | Chemical sciences Materials science | | | Organic chemistry | | Abstract | Full Text | PDF (1,163 kB) |

| A structural basis for streptomycin-induced misreading of the genetic code | | | Hasan Demirci, Frank Murphy IV, Eileen Murphy, Steven T. Gregory, Albert E. Dahlberg and Gerwald Jogl | | | The antibiotic streptomycin increases errors in protein translation, but it is unclear how streptomycin exerts its effect on the ribosome. Demirci et al. present X-ray crystal structures that reveal conformational changes induced by streptomycin, which may inspire future efforts in antibiotics design. | | | 15 Jan | Nat Commun 4:1355 doi:10.1038/ncomms2346 (2013) | | | Biological sciences Molecular biology | | | | Abstract | Full Text | PDF (3,875 kB) |

Yang and Zhi-Ren Liu | | | Cell migration requires motor protein-driven delivery of proteins to the leading edge. This study shows that p68 RNA helicase behaves as a microtubule-based motor upon binding calmodulin, and that blocking this interaction inhibits cancer cell metastasis. | | | 15 Jan | Nat Commun 4:1354 doi:10.1038/ncomms2345 (2013) | | | Biological sciences Cancer | | | Cell biology | | Abstract | Full Text | PDF (2,755 kB) |

In this study, a biophysical characterization of a novel protein-only variant of RNase P, known as PRORP (PROteinaceous RNase P), reveals that transfer RNA recognition by PRORP is similar to that by ribonucleoprotein RNase P. | | | 15 Jan | Nat Commun 4:1353 doi:10.1038/ncomms2358 (2013) | | | Biological sciences Biophysics | | | Molecular biology | | Abstract | Full Text | PDF (1,190 kB) |

Bressan, Jose M. Pardo, Hans J. Bohnert and Dae-Jin Yun | | | The flowering time and clock-related protein GIGANTEA has been broadly implicated in the development and physiology of plants. Kim and colleagues study Arabidopsis and find that GIGANTEA modulates salt stress via the release of the protein kinase SOS2, which is required for salt tolerance. | | | 15 Jan | Nat Commun 4:1352 doi:10.1038/ncomms2357 (2013) | | | Biological sciences Plant sciences | | Abstract | Full Text | PDF (3,149 kB) |

Oelstrom and Baron Chanda | | | In outwardly rectifying potassium channels, depolarization initiates conformational changes in voltage-sensing domains. Goldschen-Ohm et al. find that movement of three specific domains correlates with conductance levels, and rearrangements of a fourth domain results in preinactivation subconductance states. | | | 15 Jan | Nat Commun 4:1350 doi:10.1038/ncomms2356 (2013) | | | Biological sciences Biophysics | | | Neuroscience | | Abstract | Full Text | PDF (2,132 kB) |
