Publication number: 20100216651Abstract: Cypoviruses and baculoviruses are notoriously difficult to eradicate because the virus particles are embedded in micron-sized protein crystals called polyhedra. The remarkable stability of polyhedra means that like bacterial spores these insect viruses remain infectious for years in soil. Although these unique in vivo protein crystals have been extensively characterized since the early 1900s, their atomic organization remains elusive. Here we describe the 2 crystal structure of both recombinant and infectious silkworm cypovirus polyhedra determined using 5-12 micron crystals purified from insect cells. These are the smallest crystals yet used for de novo X-ray protein structure determination. It was found that polyhedra are made of trimers of the viral polyhedrin protein and contain nucleotides. Although the shape of these building blocks is reminiscent of some capsid trimers, polyhedrin has a new fold and has evolved to assemble in vivo into 3-D cubic crystals rather than icosahedral shells.Type: ApplicationFiled: February 28, 2008Publication date: August 26, 2010Applicants: National University Corporation Kyoto Institute of Technology, Protein Crystal CorporationInventors: Peter Metcalf, Fasseli Joseph Coulibaly, Hajime Mori, Norio Hamada, Keiko Ikeda, Yui Lam Elaine Chiu, Hiroshi Ijiri

Publication number: 20100203332Abstract: The present invention provides a method for producing a PTFE fiber that makes it possible, unlike the emulsion spinning process, to obtain a polytetrafluoroethylene (PTFE) fiber, particularly a long PTFE fiber, without using a matrix material, is more productive than conventional production methods such as a slit yarn process, and is capable of enhancing mechanical properties and the degree of freedom in diameter of the obtained fiber. The method for producing the PTFE fiber of the present invention includes the step of reducing a diameter of a string-shape PTFE-containing solid material (a first solid material) by drawing the first solid material at a temperature equal to or higher than a melting point of PTFE. The first solid material can be obtained from a PTFE-containing solid material (a second solid material) containing water and a surfactant, by reducing an amount of the water contained in the second solid material.Type: ApplicationFiled: June 16, 2008Publication date: August 12, 2010Applicants: Nitto Denko Corporation, National University Corporation Kyoto Institute of TechnologyInventors: Daisuke Kitagawa, Takashi Wano, Hideki Yamane, Yoshihito Takagi
