    Abstract We realize an experimental facility for cooling and trapping strontium (Sr) atoms and measure the Land\'e g factor of $^{3}$D$_{1}$ of $^{88}$Sr. Thanks to a novel repumping scheme with the $^{3}$P$_{2}$$\rightarrow$$^{3}$S$_{1}$ and $^{3}$P$_{0}$$\rightarrow$$^{3}$D$_{1}$ combination and the permanent magnets based self-assembled Zeeman slower, the peak atom number in the continuously repumped blue MOT is enhanced by a factor of 15 with respect to the non-repumping case, and reaches $\sim$1 billion. Furthermore, using the resolved-sideband Zeeman spectroscopy, the Land\'e g factor of $^{3}$D$_{1}$ is measured to be 0.4995(88) showing a good agreement with the theoretical value of 0.4988. The results will have an impact on various applications including atom laser, dipolar interactions, quantum information and precision measurements.

    Abstract The ratio of the electric and magnetic form factors of the proton G(E(p))/G(M(p)), which is an image of its charge and magnetization distributions, was measured at the Thomas Jefferson National Accelerator Facility (JLab) using the recoil polarization technique. The ratio of the form factors is directly proportional to the ratio of the transverse to longitudinal components of the polarization of the recoil proton in the elastic e(-->)p---> e(-->)p reaction. The new data presented span the range 3.5< Q(2)< 5.6 GeV(2) and are well described by a linear Q(2) fit. Also, the ratio sqrt[Q(2)] F(2(p))/F(1(p)) reaches a constant value above Q(2) = 2 GeV(2).

    Abstract High-precision measurements of the proton elastic form-factor ratio, mu pG p E/G p M, have been made at four-momentum transfer, Q2, values between 0.2 and 0.5 GeV2. The new data, while consistent with previous results, clearly show a ratio less than unity and significant differences from the central values of several recent phenomenological fits. By combining the new form-factor ratio data with an existing cross-section measurement, one finds that in this Q2 range the deviation from unity is primarily due to G p E being smaller than expected.

    Abstract To operate as a rotary motor, the ATP-hydrolyzing domain of the vacuolar H(+)-ATPase must be connected to a fixed structure in its membrane-bound proton pump domain by a mechanical stator. Although low-resolution structural data and spectroscopic analysis indicate that a filament-like subunit E/subunit G heterodimer performs this role, more detailed information about the relative arrangement of these subunits is limited. We have used a site-directed cross-linking approach to show that, in both bacterial and yeast V-type ATPases, the N-terminal alpha-helical segments of the G and E subunits are closely aligned over a distance of up to 40 A. Furthermore, cross-linking coupled to mass spectrometry shows that the C-terminal end of G is anchored at the C-terminal globular domain of subunit E. These data are consistent with a stator model comprising two approximately 150 A long parallel alpha-helices linked to each other at both ends, stabilized by a coiled-coil arrangement and capped by the globular C-terminal domain of E that connects the cytoplasmic end of the helical structure to the V-ATPase catalytic domain.

    Abstract: ... that subunits Vma5p (subunit C) and Vma10p (subunit G), expressed as glutathione-S-transferase fusion proteins ... in E. coli, are both able to interact strongly with Vma4p (subunit E) expressed in a cell-free system ...

    Abstract Vacuolar H(+)-ATPases (V-ATPases) are multi-subunit membrane proteins that couple ATP hydrolysis to the extrusion of protons from the cytoplasm. Although they share a common macromolecular architecture and rotational mechanism with the F(1)F(0)-ATPases, the organization of many of the specialized V-ATPase subunits within this rotary molecular motor remains uncertain. In this study, we have identified sequence segments involved in linking putative stator subunits in the Saccharomyces V-ATPase. Precipitation assays revealed that subunits Vma5p (subunit C) and Vma10p (subunit G), expressed as glutathione-S-transferase fusion proteins in E. coli, are both able to interact strongly with Vma4p (subunit E) expressed in a cell-free system. GST-Vma10p also associated with Vma2p and Vma1p, the core subunits of the ATP-hydrolyzing domain, and was able to self-associate to form a dimer. Mutations within the first 19-residue region of Vma4p, which disrupted interaction with Vma5p in vitro, also prevented the Vma4p polypeptide from restoring V-ATPase function in a complementation assay in vivo. These mutations did not prevent assembly of Vma5p (subunit C) and Vma2p (subunit B) into an inactive complex at the vacuolar membrane, indicating that Vma5p must make multiple interactions involving other V-ATPase subunits. A second, highly conserved region of Vma4p between residues 19 and 38 is involved in binding Vma10p. This region is highly enriched in charged residues, suggesting a role for electrostatic effects in Vma4p-Vma10p interaction. These protein interaction studies show that the N-terminal region of Vma4p is a key factor not only in the stator structure of the V-ATPase rotary molecular motor, but also in mediating interactions with putative regulatory subunits.
