Mate Transporter

Multidrug and toxic compound extrusion (MATE) transporters, one of the multidrug exporter families, efflux xenobiotics towards the extracellular side of the membrane. Since MATE transporters expressed in bacterial pathogens contribute to multidrug resistance, they are important therapeutic targets. Here, a MATE-transporter homologue fromVibrio cholerae, VcmN, was overexpressed inEscherichia coli, purified and crystallized in lipidic cubic phase (LCP). X-ray diffraction data were collected to 2.5 Å resolution from a single crystal obtained in a sandwich plate. The crystal belonged to space groupP212121, with unit-cell parametersa= 52.3,b= 93.7,c= 100.2 Å. As a result of further LCP crystallization trials, crystals of larger size were obtained using sitting-drop plates. X-ray diffraction data were collected to 2.2 Å resolution from a single crystal obtained in a sitting-drop plate. The crystal belonged to space groupP212121, with unit-cell parametersa= 61.9,b= 91.8,c= 100.9 Å. The present work provides valuable insights into the atomic resolution structure determination of membrane transporters.

Abstract In the course of our investigation of the ternary system K-Au-Sn we obtained the new compound KAu4Sn2. Its crystal structure has been determinated from single crystal X-ray diffraction data. It crystallizes in the tetragonal space group 1̅4̅c2 with unit-cell parameters a = 884.7 and c = 817.8 pm and Z = 4. The structure is comparable to that of the Tl2Se.

AbstractThe crystal structure of the copper aluminium phosphate mineral sieleckiite, Cu3Al4(PO4)2 (OH)12·2H2O, from the Mt Oxide copper mine, Queensland, Australia was solved from single-crystal X-ray diffraction data utilizing synchrotron radiation. Sieleckiite has monoclinic rather than triclinic symmetry as previously reported and is space group C2/m with unit-cell parameters a = 11.711(2), b = 6.9233(14), c = 9.828(2) Å, β = 92.88(3)°, V = 795.8(3) Å3and Z = 2. The crystal structure, which has been refined to R1 = 0.0456 on the basis of 1186 unique reflections with Fo > 4σF, is a framework of corner-, edge- and face- sharing Cu and Al octahedra and PO4 tetrahedra.
