    Description: eIF5 is the GTPase activating protein (GAP) for the eIF2·GTP·Met-tRNA i Met ternary complex with a critical role in initiation codon selection. Previous work suggested that the eIF5 mutation G31R/SUI5 elevates initiation at UUG codons by increasing GAP function. Subsequent work implicated eIF5 in rearrangement of the preinitiation complex (PIC) from an open, scanning conformation to a closed state at AUG codons, from which P i is released from eIF2·GDP·P i . To identify eIF5 functions crucial for accurate initiation, we investigated the consequences of G31R on GTP hydrolysis and P i release, and the effects of intragenic G31R suppressors on these reactions, and on the partitioning of PICs between open and closed states. eIF5-G31R altered regulation of P i release, accelerating it at UUG while decreasing it at AUG codons, consistent with its ability to stabilize the closed complex at UUG. Suppressor G62S mitigates both defects of G31R, accounting for its efficient suppression of UUG initiation in G31R,G62S cells; however suppressor M18V impairs GTP hydrolysis with little effect on PIC conformation. The strong defect in GTP hydrolysis conferred by M18V likely explains its broad suppression of Sui – mutations in numerous factors. We conclude that both of eIF5's functions, regulating P i release and stabilizing the closed PIC conformation, contribute to stringent AUG selection in vivo .

    Description: Meiotic crossovers (COs) are tightly regulated to ensure that COs on the same chromosome are distributed far apart (crossover interference, COI) and that at least one CO is formed per homolog pair (CO homeostasis). CO formation is controlled in part during meiotic double-strand break (DSB) creation in Caenorhabditis elegans, but a second level of control must also exist because meiotic DSBs outnumber COs. We show that the antirecombinase RTEL-1 is required to prevent excess meiotic COs, probably by promoting meiotic synthesis-dependent strand annealing. Two distinct classes of meiotic COs are increased in rtel-1 mutants, and COI and homeostasis are compromised. We propose that RTEL-1 implements the second level of CO control by promoting noncrossovers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770885/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4770885/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Youds, Jillian L -- Mets, David G -- McIlwraith, Michael J -- Martin, Julie S -- Ward, Jordan D -- ONeil, Nigel J -- Rose, Ann M -- West, Stephen C -- Meyer, Barbara J -- Boulton, Simon J -- Canadian Institutes of Health Research/Canada -- Cancer Research UK/United Kingdom -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Mar 5;327(5970):1254-8. doi: 10.1126/science.1183112.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉DNA Damage Response Laboratory, London Research Institute, Cancer Research UK, Clare Hall, South Mimms, EN6 3LD, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20203049" target="_blank"〉PubMed〈/a〉

    Description: The midguts of adult workers of the higher termite species Macrotermes natalensis contain the entire set of digestive enzymes required for the digestion of native cellulose. The C(x)-cellulases and the beta-glucosidases are produced, at least in part, by the termite's own midgut epithelium and salivary glands. The C(1)-cellulases, on the other hand, are acquired by the termites when they feed on a fungus that grows in their nests. We propose that the involvement of acquired digestive enzymes could serve as the basis for a general strategy of resource utilization and further suggest that the acquisition of digestive enzymes may be a widespread phenomenon among mycophagous invertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martin, M M -- Martin, J S -- New York, N.Y. -- Science. 1978 Mar 31;199(4336):1453-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17796679" target="_blank"〉PubMed〈/a〉

    Notes: A hyperthermal beam of state-selected NO+ X Σ+(v=0–6) ions is scattered on a clean, well-characterized GaAs(110) surface. The threshold for the appearance of scattered O− ions occurs at a collision energy of 25 eV. Vibrational energy proves to be an order of magnitude more effective than translational energy in enhancing the yield in this channel.

    Notes: The scattering of state-selected NO+(X 1Σ+, v=0–6) on GaAs(110) was explored across the hyperthermal energy region. Relative yields and velocity distributions for scattered anionic products NO−(X 3Σ−, v=0) and O−(2P) were measured as a function of the number of vibrational quanta and collision energy for NO+(X 1Σ+, v=0–6) incident on the surface. Facile neutralization along the inbound trajectory forms vibrationally excited NO(2Π) immediately prior to surface impact. Electron attachment to form NO−(X 3Σ−, v=0) occurs near the distance of closest approach between the molecule and surface. With regard to O−(2P) emergence, a collision-induced dissociation mechanism is consistent with the observed 25 eV threshold. Incident vibrational energy is as much as ten times more effective than translational energy in forming O−(2P). This paper represents the first experimental investigation into the effect of vibrational energy on electron transfer and dissociation of ions at surfaces and highlights the unique interplay between translational and vibrational motions in an ion/surface encounter.

    Notes: Hyperthermal energy reactions of NO+ with Ag(111) were studied as a function of collision energy and the incident diatom's internuclear-axis direction. Laser photoselection via (1+1') resonance enhanced multiphoton ionization (REMPI) prepared an aligned distribution of NO+(X 1Σ+, Etrans, v=0, J) prior to the molecules impact with the surface. The emergence of scattered O− products was enhanced when NO+ approached the surface with an "end-on'' rather than a "side-on'' orientation. Moreover, the magnitude of the reaction's alignment preference increased with decreasing collision energy. The appearance threshold for O− was approximately 20 eV. Classical trajectory calculations demonstrated that these results are consistent with a collision-induced dissociation mechanism mediated by both vibrational and rotational excitation upon impact. Reorientation of the internuclear axis during the collision drastically affects the simulated dissociation dynamics. No alignment preference for scattered NO− emergence could be discerned from the experiments. As a complement, the angular momentum mechanics are provided to predict the internuclear-axis distribution of ions created via two-photon REMPI. © 1995 American Institute of Physics.
