Article Synopsis
- Gram-negative bacteria use the proton motive force (PMF) in their inner membrane to maintain their cell envelope, crucial for survival and division.
- The study presents detailed cryo-EM images of the TolQ protein in two states: one when it's not bound to TolR (apo form) and another when it is bound, showing significant structural changes.
- The findings reveal how the TolQ-TolR complex functions like a rotor-stator system, enhancing our understanding of the mechanisms behind bacterial cell envelope integrity and division.
Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polarization. The asymmetry depends on the azimuthal angles of both the pion (phi) and the target spin axis (phi(S)) about the virtual-photon direction and relative to the lepton scattering plane. The extracted Fourier component sin((phi+phi(S))(pi)(UT) is a signal of the previously unmeasured quark transversity distribution, in conjunction with the Collins fragmentation function, also unknown.
