- The Taiwan APCST contract beamline BL12B2 is a multiple-purpose beamline, which is designed to accommodate experiments of x-ray absorption spectroscopy, protein crystallography, x-ray scattering, and micro-beam diffraction. The beamline optics is designed to provide both white beam and monochromatic beam of energies from 5 to 70 keV. Besides high-resolution x-ray absorption and scattering, special experimental capabilities at this beamline will include quick-EXAFS, high-throughput MAD, and micro-beam high-pressure diffraction. The beamline installation was completed in September 2000. The radiation and safety test was passed in early October and the beamline has been under commissioning since then. In this report, we present in brief the beamline design, some construction highlights, and our initial commission results.

- Structure of the calcium pump of muscle sarcoplasmic reticulum was determined at 2.6 Å resolution by X-ray crystallography. This is the first atomic structure of the cation pumps called P-type ATPases. Because the crystals were very thin, the use of SPring-8 was vital to this work. The structure of the Ca2+ -pump is overviewed very briefly.

- The crystal structure of bovine rhodopsin, a G-protein coupled receptor was solved by MAD phasing using 3.3Å resolution MAD data set collected at SPring-8 BL45XU, and followed by the structural refinement at 2.8Åresolution using a twinned crystal data collected at APS 19-ID.
