    Defining protein interactions with yeast actin in vivo (1995)
    [s.l.] : Nature Publishing Group
    Nature structural biology 2 (1995), S. 28-35 
    Details
    ISSN: 1072-8368
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Medicine
    Notes: [Auszug] Using the two-hybrid protein interaction reporter system, actin, profilin, Srv2p and two SH3-containing proteins are found to bind yeast actin in vivo. When tested for ability to interact with 35 actin mutations distributed over the monomer surface, distinct subsets of mutations characteristic for ...

    Notes: [Auszug] The requirements for any such "geological" experiment are that the interacting material has been sufficiently deeply buried that the neutrino effect is not swamped by cosmic-ray interactions, that the cover has been in place long enough for any previously produced 81Kr to decay, that the ...

    Notes: [Auszug] The maximum thermodynamic efficiency permitted for extracting energy from direct sunlight must be higher than that permitted for diffuse sunlight of the same intensity, since loss of directivity is evidently an irreversible process. But what are the numerical values of these two maximum ...

    Notes: [Auszug] Furthermore, infrared spectra of phosphate adsorbed on goethite show differences according to the suspension pH at which the sample was prepared1,3. These probably arise from different states of protonation of the adsorbed phosphate, but the results have been difficult to interpret. The possibility ...

    Notes: [Auszug] Proteus bacteria are unusual in that they readily swarm out from the inoculum point on the surface of most agar media. Despite study by many workers there are several aspects of this swarming that are not understood. We have been considering one of these aspects, namely the behaviour of two swarms ...

    Notes: [Auszug] To trace the evolutionary improvement of an enzyme in molecular terms and to watch the stepwise development of its catalytic apparatus, we need an enzyme susceptible to directed selective pressure towards an altered catalytic function. So that mutational changes may be fully inter-pretable, the ...

    Notes: [Auszug] THE name of sassafras tea conjures up thoughts of early days in North America, of folk medicine, and of a tree whose leaves, charmingly enough, grow in three different shapes on the same branch?some are three-fingered, some are mitten-shaped, and some are just oval. The name is Spanish, but the ...
