    Description: Theileria annulata and T. parva are closely related protozoan parasites that cause lymphoproliferative diseases of cattle. We sequenced the genome of T. annulata and compared it with that of T. parva to understand the mechanisms underlying transformation and tropism. Despite high conservation of gene sequences and synteny, the analysis reveals unequally expanded gene families and species-specific genes. We also identify divergent families of putative secreted polypeptides that may reduce immune recognition, candidate regulators of host-cell transformation, and a Theileria-specific protein domain [frequently associated in Theileria (FAINT)] present in a large number of secreted proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pain, Arnab -- Renauld, Hubert -- Berriman, Matthew -- Murphy, Lee -- Yeats, Corin A -- Weir, William -- Kerhornou, Arnaud -- Aslett, Martin -- Bishop, Richard -- Bouchier, Christiane -- Cochet, Madeleine -- Coulson, Richard M R -- Cronin, Ann -- de Villiers, Etienne P -- Fraser, Audrey -- Fosker, Nigel -- Gardner, Malcolm -- Goble, Arlette -- Griffiths-Jones, Sam -- Harris, David E -- Katzer, Frank -- Larke, Natasha -- Lord, Angela -- Maser, Pascal -- McKellar, Sue -- Mooney, Paul -- Morton, Fraser -- Nene, Vishvanath -- O'Neil, Susan -- Price, Claire -- Quail, Michael A -- Rabbinowitsch, Ester -- Rawlings, Neil D -- Rutter, Simon -- Saunders, David -- Seeger, Kathy -- Shah, Trushar -- Squares, Robert -- Squares, Steven -- Tivey, Adrian -- Walker, Alan R -- Woodward, John -- Dobbelaere, Dirk A E -- Langsley, Gordon -- Rajandream, Marie-Adele -- McKeever, Declan -- Shiels, Brian -- Tait, Andrew -- Barrell, Bart -- Hall, Neil -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 1;309(5731):131-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK. ap2@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15994557" target="_blank"〉PubMed〈/a〉

    Description: The plant hormone auxin regulates various developmental processes including root formation, vascular development, and gravitropism. Mutations within the AUX1 gene confer an auxin-resistant root growth phenotype and abolish root gravitropic curvature. Polypeptide sequence similarity to amino acid permeases suggests that AUX1 mediates the transport of an amino acid-like signaling molecule. Indole-3-acetic acid, the major form of auxin in higher plants, is structurally similar to tryptophan and is a likely substrate for the AUX1 gene product. The cloned AUX1 gene can restore the auxin-responsiveness of transgenic aux1 roots. Spatially, AUX1 is expressed in root apical tissues that regulate root gravitropic curvature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bennett, M J -- Marchant, A -- Green, H G -- May, S T -- Ward, S P -- Millner, P A -- Walker, A R -- Schulz, B -- Feldmann, K A -- New York, N.Y. -- Science. 1996 Aug 16;273(5277):948-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Warwick, Coventry, CV4 7AL, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8688077" target="_blank"〉PubMed〈/a〉

    Notes: The structure of the HBr OCS van der Waals complex has been studied by Fourier transform microwave spectroscopy. The ground state complex is hydrogen bound and quasilinear with SCO–HBr atomic ordering. Spectra from five different isotopomers were observed and assigned. The wide amplitude bending angle of the hydrogen bromide was calculated from the nuclear quadrupole coupling constant χaa to be 25.2°. Second order quadrupole effects, centrifugal distortion in the nuclear quadrupole coupling constant Dχ, a spin–rotation interaction, CBr, and a spin–spin interaction, Daa, were all included in the Hamiltonian. The following spectroscopic constants have been determined for the H79Br OCS isotopomer: B¯=488.7948(4) MHz; DJ=2.167(6) kHz; HJ=1.19(3) Hz; χaa=387.14(1) MHz; Dx=6.79(14) kHz; CBr=0.55(13) kHz; and Daa=7.7(1.2) kHz. © 1995 American Institute of Physics.

    Notes: We have investigated the structure and dynamics of the weakly bound complex of the four bromine isotopomers of HBr DBr, using pulsed-jet Fourier transform microwave spectroscopy. In addition, the equilibrium geometry, intermolecular energy, and vibrational force constants for the dimer have been calculated at the MP2 level using a large basis set containing bond functions. In the hydrogen halide dimers, allowed transitions are across the inversion doublet caused by the geared interchange of the donor and acceptor of the hydrogen bond. While in the classic study of (HF)21 it was observed that this splitting results in an inversion frequency in the microwave region of the spectrum, in (HCl)2 and (HBr)2 that the lower inversion barrier, results in an inversion frequency in the infrared. In order to investigate the hydrogen bromide dimer with the high precision allowed by an FT microwave experiment, we have "quenched" the inversion motion by substituting deuterium for one of the hydrogens. The Br–Br distance in the complex is 4.136 Å. Using measurements of the nuclear quadrupole coupling constants of the bromine nuclei, the wide amplitude bending motions of the hydrogen-bonded deuterium have been determined as have the wide amplitude bending angle of the nonbonding hydrogen atom. The Br–Br–D angle undergoes excursions of 28° about zero, and the H–Br–Br angle oscillates 25° about its 90° equilibrium angle. © 1997 American Institute of Physics.

    Notes: The rotational spectrum of the O3–CH4 complex has been measured in a molecular beam using a pulsed-nozzle Fourier-transform microwave spectrometer. An a-type pure-rotation and a c-type rotation-inversion electric-dipole spectrum is observed, complicated by the nearly free internal rotation of the CH4 top and the inversion tunneling of the O3. The nuclear-spin statistics of the equivalent oxygen nuclei leads to only one tunneling component existing for each rotation–internal-rotation state, indicating that the transition state has a heavy-atom, C2v-symmetry geometry. The tunneling splitting is determined to be 30 to 40 MHz, dependent on the CH4 internal-rotor state. Only two of the three methane internal-rotor states have been assigned. These two states of A and F symmetry have asymmetric-rotor energy-level structures, weakly perturbed by the ozone-inversion tunneling. The zero-point structure of the complex has a heavy-atom plane of symmetry with the two terminal O atoms equidistant above and below this plane. The angle between the line joining the center of masses of the two subunits and the O3, C2 axis is 118.2(5)°, with the central O directed away from the CH4. The shortest O–C separation is 3.57 Å. The geometry of the complex suggests two outcomes for the reaction of an O atom produced by 267 nm photolysis of O3 in the complex (assuming that the initial O3 photodissociation dynamics are not perturbed by complexation), either nonreaction or reaction by stripping of a hydrogen atom at high impact parameters, leading to fast, highly rotationally excited, OH product. © 2000 American Institute of Physics.
