  • Patent number: 8554493
    Abstract: 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.

  • Patent number: 4448518
    Abstract: A photosensitive material holder for an upright printing machine, in which an upright photosensitive material holder plate is adapted to be moved in a direction of its one side, and which includes guide means by which the top of the upright photosensitive material holder plate is inclined rearwards when the upright photosensitive material holder plate is moved to its side direction.

  • Patent number: 4234251
    Abstract: An automatic masking device for use in a composer, wherein an original picture is held against a transparent plate, which comprises a plurality of opaque maskingsheets which are adapted to move inwards along the surface of the transparent plate from its edges, driven by drive means which is controlled by detectors which are mounted on the inside edges of at least some of the masking sheets.
