linkurl:1. New moves for myosin; In order to transport intracellular cargo within a cell, the motor protein myosin V walks along actin filaments by sweeping one of its arms over the other in a series of microscopic steps, researchers confirmed using high-speed atomic force microscopy. This highly detailed, real-time imaging also revealed new features of the myosin walk, such as "stomping," where one of the arms briefly detaches from the actin, and then reattaches in the same spot. N. Kodera et al., linkurl:Nature,; 468:72-6, 2010. Evaluated by Thomas Meier, Max Planck Institute of Biophysics; Yamini Dalal, National Cancer Institute; Fred D Mast and Richard A Rachubinski, Univ. of Alberta; Erik Sahai, Cancer Research UK. linkurl:Free F1000 Evaluation; linkurl:2. Eukaryotic ribosome unveiled; The long-elusive crystal structure of the translational machinery in yeast reveals unique interactions within and between the ribosome's two subunits and promises to lead to a better understanding of protein synthesis in eukaryotes. A. Ben-Shem et al., linkurl:Science,; 330:1203-9, 2010. Evaluated by Robert Batey, Univ. of Colorado at Boulder; Dmitri Ermolenko and George Makhatadze, Rensselaer Polytechnic Institute. linkurl:Free F1000 Evaluation; linkurl:3. Elusive intermediate #1 captured; The existence of the fabled intermediate form of cytochrome P450 -- long suspected of catalyzing the oxidation reactions required for metabolizing the majority of drugs in the liver, among other things -- has finally been confirmed using isolates from a thermophilic bacterium. J. Rittle and M.T. Green, linkurl:Science,; 330:933-7, 2010. Evaluations by Ivo Feussner, Georg August Univ. G?ttingen, Germany; Russ Hille, UC Riverside; Kap-Sun Yeung and Nicholas Meanwell, Bristol Myers Squibb. linkurl:Free F1000 Evaluation; linkurl:4. Elusive intermediate #2 captured; Researchers visualize the molecular structure of a short-lived folding intermediate of the FF domain of a human protein with a combination of NMR spectroscopy and powerful computational methods, providing a novel technique for studying the atomic details of protein folding pathways. D.M. Korzhnev, et al., linkurl:Science,; 329:1312-6, 2010. Evaluations by Robert Powers, Univ. Nebraska; Mikael Akke, Lund University, Sweden. linkurl:Free F1000 Evaluation; linkurl:5. Ribosome assembly up close; The self-assembly of the 30S subunit of bacterial ribosomes is observed in vitro with a novel use of electron microscopy combined with mass spectrometry -- revealing clues about how the process occurs in vivo and offering a powerful method for studying the assembly of other biological complexes. A.M. Mulder, et al., linkurl:Science,; 330:673-7, 2010. Evaluations by Pascale Legault, Univ. Montreal; Mikael Akke, Lund University, Sweden. linkurl:Free F1000 Evaluation; linkurl:6. Growth factor mystery solved; Why the binding of one ligand to epidermal growth factor receptors (EGFR) reduces the receptor's ability to take on a second has baffled researchers for decades. Now studies of the Drosophila EGFR reveal that binding of the first ligand changes the conformation of the dimeric receptor, obstructing the unoccupied site and making it harder for a second ligand to latch on. D. Alvarado, et al., linkurl:Cell,; 142:568-79, 2010. Evaluations by Yue Sun and Richard Anderson, Univ. Wisconsin-Madison; Andrew Beenken and Moosa Mohammadi, NYU Langone Medical Center; Arthur Christopoulos, Monash Univ., Australia. linkurl:Free F1000 Evaluation;

linkurl:7. New class of antimalarial agents; Screening 12,000 natural compounds, researchers identified a novel family of drugs, dubbed spiroindolones, capable of killing the blood stages of two Plasmodium parasites with a single, small dose in mice, providing a promising candidate for treating malaria, which claims more than a million lives annually. R.A. Oliveira et al., linkurl:Science,; 329:1175-80, 2010. Evaluations by David Triggle, SUNY at Buffalo; Dominique Soldati, Univ. of Geneva; Karin Romisch, Saarland Univ., Germany. linkurl:Free F1000 Evaluation; The F1000 Top 7 is a snapshot of the highest ranked articles from a 30-day period on Faculty of 1000 Biochemistry, as calculated on January 3rd, 2010.
