  • Patent number: 7544498
    Abstract: In accordance with the present invention, a novel aromatic prenyltransferase, Orf2 from Streptomyces sp. strain CL190, involved in naphterpin biosynthesis has been identified and the structure thereof elucidated. This prenyltransferase catalyzes the formation of a C—C bond between a prenyl group and a compound containing an aromatic nucleus, and also displays C—O bond formation activity. Numerous crystallographic structures of the prenyltransferase have been solved and refined, e.g., (1) prenyltransferase complexed with a buffer molecule (TAPS), (2) prenyltransferase as a binary complex with geranyl diphosphate (GPP) and Mg2+, and prenyltransferase as ternary complexes with a non-hydrolyzable substrate analogue, geranyl S-thiolodiphosphate (GSPP) and either (3) 1,6-dihydroxynaphthalene (1,6-DHN), or (4) flaviolin (i.e., 2,5,7-trihydroxy-1,4-naphthoquinone, which is the oxidized product of 1,3,6,8-tetrahydroxynaphthalene (THN)). These structures have been solved and refined to 1.5 ?, 2.25 ?, 1.95 ? and 2.

  • Patent number: 7460964
    Abstract: The invention relates to a technique for reducing computation time for force vector calculation. A force vector reconstruction method that uses an optical tactile sensor, comprises a step for obtaining a marker image by taking an image of behavior of colored markers when an object contacts a contact surface of an elastic body, a step of obtaining information relating to the marker behavior from the marker image, the information being more than the number of force vectors to be obtained, and a step of obtaining force vectors as outputs by inputting information relating to the obtained marker behavior to a transfer function. The step of obtaining force vectors comprises calculating force vectors using only information relating to behavior of markers neighboring region A1 of a position A where it is desired to obtain force vectors.

  • Patent number: 7455962
    Abstract: Mouse PCLP1 was identified by expression cloning with the use of a monoclonal antibody against a surface antigen of a cell line derived from mouse AGM. By fractionating PCLP1-positive/CD45-negative cells and culturing them in vitro, it was clarified that these cells differentiate into endothelial-like cells, angioblast-like cells, and hematopoietic cells. By transferring the PCLP1-positive/CD45-negative cells into a mouse defective in the hematopoietic function, the hematopoietic system was reconstructed over a long period of time. These facts indicate that the PCLP1-positive/CD45-negative cells contain mammalian hemangioblasts capable of expressing the activity as long-term repopulating hematopoietic stem cells (LTR-HSC). The present invention provides a method for preparing a cell fraction containing hemangioblasts, the cell fraction prepared by the method, and use of this cell fraction.

  • Publication number: 20080220517
    Abstract: A technique for controlling membrane denaturation reactions other than physical shear force was developed. For example, the present invention provides, a method for causing membrane disruption at a specific site by reacting a stimulus such as light with a compound that is activated by the stimulus, where the reaction occurs on a membrane such as a biomembrane. It also provides a membrane structure such as cells in which a specific site has been disrupted, which are obtained by the present method. Introduction of substances such as genes also became possible by using this membrane structure. Further provided is a membrane-destroying member for disrupting a membrane at a specific site. Thus, the present invention enabled, for example, easy membrane penetration using components constituting microelectrodes, micromanipulators, and microinjectors, which were conventionally hardly usable in penetrating cell membranes.
