Knight, Yumin Wang, Bob Zheng, Nicholas S. King, Lisa V. Brown, Zheyu Fang, Peter Nordlander and Naomi J. Halas | | | Plasmons excited in gratings create strong resonant absorptions that depend on the nanostructure period. By patterning a gold grating on a silicon substrate, Sobhani et al. exploit plasmon-induced hot electron photocurrent generation to create a narrowband infrared photodetector with greatly enhanced absorption efficiency. | | | 27 Mar | Nat Commun 4:1643 doi:10.1038/ncomms2642 (2013) | | | Physical sciences Applied physics | | | Nanotechnology Optical physics | | | | Abstract | Full Text | PDF (1,056 kB) |

| CSN- and CAND1-dependent remodelling of the budding yeast SCF complex OPEN | | | Aleksandra Zemla, Yann Thomas, Sylwia Kedziora, Axel Knebel, Nicola T. Wood, Gwenaël Rabut and Thimo Kurz | | | CAND1 promotes the activity of Cullin–RING ubiquitin ligases, but binds exclusively to inactive unneddylated forms of the enzyme. By identifying a simple means to reversibly activate this complex in budding yeast, Zemla et al. resolve this paradox and show that CAND1 acts as an exchange factor for substrate adaptors. | | | 27 Mar | Nat Commun 4:1641 doi:10.1038/ncomms2628 (2013) | | | Biological sciences Biochemistry | | | Cell biology | | Abstract | Full Text | PDF (1,573 kB) |
