In vitro reconstruction of tetronate RK-682 biosynthesis
The protein phosphatase inhibitor RK-682 is one of a number of potentially valuable tetronate polyketide natural products. Understanding how the tetronate ring is formed has been frustrated by the inaccessibility of the putative substrates. We report the heterologous expression of rk genes in Saccharopolyspora erythraea and reconstitution of the RK-682 pathway using recombinant enzymes, and we ...
متن کاملImplications of the RK and RK∗ anomalies
We discuss the implications of the recently reported RK and RK∗ anomalies, the lepton flavor non-universality in the B → Kll and B → Kll. Using two sets of hadronic inputs of form factors, we perform a fit of the new physics to the RK and RK∗ data, and significant new physics contributions are found. We propose to study the lepton flavor universality in a number of related rare B,Bs, Bc and Λb ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Npgrj_nn_1905 682..684
The firing pattern of entorhinal ‘grid cells’ is thought to provide an intrinsic metric for space. We report a strong experiencedependent environmental influence: the spatial scales of the grids (which are aligned and have fixed relative sizes within each animal) vary parametrically with changes to a familiar environment’s size and shape. Thus grid scale reflects an interaction between intrinsi...
