Iterative phasing for fluctuation X-ray scattering [Biophysics and Computational Biology]

18-Aug-2015 | Jeffrey J. Donatelli; Peter H. Zwart; James A. Sethian, Proceedings of the National Academy of Sciences current issue, 2015

Fluctuation X-ray scattering (FXS) is an extension of small- and wide-angle X-ray scattering in which the X-ray snapshots are taken below rotational diffusion times. This technique, performed using a free electron laser or ultrabright synchrotron source, provides significantly more experimental ...

Insights into G-quadruplex specific recognition by the DEAH-box helicase RHAU: Solution structure of a peptide-quadruplex complex [Chemistry]

04-Aug-2015 | Brahim Heddi; Vee Vee Cheong; Herry Martadinata; Anh Tuân Phan, Proceedings of the National Academy of Sciences current issue, 2015

Four-stranded nucleic acid structures called G-quadruplexes have been associated with important cellular processes, which should require G-quadruplex–protein interaction. However, the structural basis for specific G-quadruplex recognition by proteins has not been understood. The DEAH ...

Study of the instability of the Poiseuille flow using a thermodynamic formalism [Applied Mathematics]

04-Aug-2015 | Jianchun Wang; Qianxiao Li; Weinan E, Proceedings of the National Academy of Sciences current issue, 2015

The stability of the plane Poiseuille flow is analyzed using a thermodynamic formalism by considering the deterministic Navier–Stokes equation with Gaussian random initial data. A unique critical Reynolds number, Rec≈2,332, at which the probability of observing puffs in the solution changes from ...

Three-ring circus without a ringmaster: Self-organization of supracellular actin ring patterns during epithelial morphogenesis [Biophysics and Computational Biology]

14-Jul-2015 | Nir S. Gov; Saoirse S. McSharry; Greg J. Beitel, Proceedings of the National Academy of Sciences current issue, 2015

Formation of patterns during development has been a long-standing puzzle. Alan Turing proposed chemical gradients as a solution to the problem (1), and many chemical signals that pattern cells have since been found. However, only recently have roles for mechanical forces in patterning become ...

Hydrodynamic collective effects of active protein machines in solution and lipid bilayers [Physics]

14-Jul-2015 | Alexander S. Mikhailov; Raymond Kapral, Proceedings of the National Academy of Sciences current issue, 2015

The cytoplasm and biomembranes in biological cells contain large numbers of proteins that cyclically change their shapes. They are molecular machines that can function as molecular motors or carry out various other tasks in the cell. Many enzymes also undergo conformational changes within their ...

Analysis of the size dependence of macromolecular crowding shows that smaller is better [Biophysics and Computational Biology]

30-Jun-2015 | Kim A. Sharp, Proceedings of the National Academy of Sciences current issue, 2015

The aqueous milieu inside cells contains as much as 30–40% dissolved protein and RNA by volume. This large concentration of macromolecules is expected to cause significant deviations from solution ideality. In vivo biochemical reaction rates and equilibria might differ significantly from those ...

Identification of a triplet pair intermediate in singlet exciton fission in solution [Chemistry]

23-Jun-2015 | Hannah L. Stern; Andrew J. Musser; Simon Gelinas; Patrick Parkinson; Laura M. Herz; Matthew J. Bruzek; John Anthony; ..., Proceedings of the National Academy of Sciences current issue, 2015

Singlet exciton fission is the spin-conserving transformation of one spin-singlet exciton into two spin-triplet excitons. This exciton multiplication mechanism offers an attractive route to solar cells that circumvent the single-junction Shockley–Queisser limit. Most theoretical descriptions of ...

Solution structure of the PsIAA4 oligomerization domain reveals interaction modes for transcription factors in early auxin response [Plant Biology]

12-May-2015 | Dhurvas Chandrasekaran Dinesh; Michael Kovermann; Mohanraj Gopalswamy; Antje Hellmuth; Luz Irina A. Calderón Villalo ..., Proceedings of the National Academy of Sciences current issue, 2015

The plant hormone auxin activates primary response genes by facilitating proteolytic removal of AUXIN/INDOLE-3-ACETIC ACID (AUX/IAA)-inducible repressors, which directly bind to transcriptional AUXIN RESPONSE FACTORS (ARF). Most AUX/IAA and ARF proteins share highly conserved C-termini mediating ...

Joint neutron crystallographic and NMR solution studies of Tyr residue ionization and hydrogen bonding: Implications for enzyme-mediated proton transfer [Biochemistry]

05-May-2015 | Ryszard Michalczyk; Clifford J. Unkefer; John-Paul Bacik; Tobias E. Schrader; Andreas Ostermann; Andrey Y. Kovalevsk ..., Proceedings of the National Academy of Sciences current issue, 2015

Human carbonic anhydrase II (HCA II) uses a Zn-bound OH−/H2O mechanism to catalyze the reversible hydration of CO2. This catalysis also involves a separate proton transfer step, mediated by an ordered solvent network coordinated by hydrophilic residues. One of these residues, Tyr7, was previously ...

Base-enhanced catalytic water oxidation by a carboxylate-bipyridine Ru(II) complex [Chemistry]

21-Apr-2015 | Na Song; Javier J. Concepcion; Robert A. Binstead; Jennifer A. Rudd; Aaron K. Vannucci; Christopher J. Dares; Michae ..., Proceedings of the National Academy of Sciences current issue, 2015

In aqueous solution above pH 2.4 with 4% (vol/vol) CH3CN, the complex [RuII(bda)(isoq)2] (bda is 2,2′-bipyridine-6,6′-dicarboxylate; isoq is isoquinoline) exists as the open-arm chelate, [RuII(CO2-bpy-CO2−)(isoq)2(NCCH3)], as shown by 1H and 13C-NMR, X-ray crystallography, and pH titrations. ...
