20100216651VIRAL POLYHEDRA COMPLEXES AND METHODS OF USE - 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. The polyhedrin trimers are extensively cross-linked in polyhedra by non-covalent interactions and pack with an exquisite molecular complementarity similar to that of antigen-antibody complexes. The resulting ultra-stable and sealed crystals shield the virus particles from environmental damage. The structure suggests that polyhedra can serve as the basis for the development of robust and versatile nanoparticles for biotechnological applications such as in cell culture systems, microarrays and biopesticides.08-26-2010

20110304246OPERATING MEMBER MOUNTING STRUCTURE - An operating member mounting structure includes a mounting plate having an inner edge defining a mounting hole, and an operating member includes a keytop and a flange which are coupled to each other by a shaft, and the flange is formed with a slit. The diameter of the flange is larger than that of the mounting hole. When the operating member is rotated and pressed down in a state that the slit receives the inner edge of the mounting hole, the flange passes over the inner edge of the mounting hole to be fully brought beneath the mounting plate. An operating shaft of an operated device is inserted into an insertion hole opened on the surface of the flange. By operating the keytop exposed from the top surface of the mounting plate, the operated device can be operated through the operating shaft.12-15-2011
