Dipole-dipole interactions in protein-protein complexes: a quantum mechanical study of the ubiquitin-Dsk2 complex
Quantum mechanical calculations are performed on the proteins that constitute the ubiquitin-Dsk2 complex whose atomic structure has been experimentally determined by NMR spectroscopy (PDB id 1WR1). The results indicate that the dipole moment vectors of the two proteins are aligned in a head-to-tail orientation while forming and angle of ~130°. Hence, attractive dipole-dipole interactions not on...
متن کاملResearch on Study Mechanical Vibrations with Data Acquisition Systems
The paper presents a new study method of mechanic vibrations with the help of the data acquisition systems. The study of vibrations with the help of data acquisition systems allows the solving of some engineering problems connected to the measurement of some parameters which are difficult to measure having in view the improvement of the technical performances of the industrial equipment or devi...
متن کاملThe Giant Nuclear Dipole Resonance
above the ground state, where a rough calculation indicates S'6 =80 Mev, a result which is in agreement with the experimentally observed position of the giant resonance. We find the p-ray width of this level to be proportional to A&, and use the width to obtain the cross sections for absorption and scattering of y rays in this region. Throughout we have neglected certain effects of the (r 'r, &...
متن کاملQuantum mechanical theory of dynamic nuclear polarization in solid dielectrics.
Microwave driven dynamic nuclear polarization (DNP) is a process in which the large polarization present in an electron spin reservoir is transferred to nuclei, thereby enhancing NMR signal intensities. In solid dielectrics there are three mechanisms that mediate this transfer--the solid effect (SE), the cross effect (CE), and thermal mixing (TM). Historically these mechanisms have been discuss...
متن کاملMechanical detection of carbon nanotube resonator vibrations.
Bending-mode vibrations of carbon nanotube resonators were mechanically detected in air at atmospheric pressure by means of a novel scanning force microscopy method. The fundamental and higher order bending eigenmodes were imaged at up to 3.1 GHz with subnanometer resolution in vibration amplitude. The resonance frequency and the eigenmode shape of multiwall nanotubes are consistent with the el...
