    摘要: Enzymes are immobilized on activated carbon supports at high load levels and with high stability by reacting an activated carbon support with a carbodiimide or an isoxazolium salt to form active organic radicals on the surface of the activated carbon support and thereafter treating the carbon support with an enzyme solution to immobilize the enzyme on the carbon support. The immobilization of enzymes on activated carbon provides immobilized enzymes which are easily handled and which are stabilized against denaturation by hydrogen peroxide.

    摘要: Enzymes are immobilized on activated carbon supports at high load levels and with high stability by a procedure whereby a carbon support is first activated with a water-soluble carbodiimide derivative which forms a highly reactive intermediate with carboxyl and other active organic radicals on the surface of the carbon support; thereafter the complex of the carbon and carbodiimide is treated with an enzyme solution whereby the enzyme displaces the carbodiimide and forms a carbon-enzyme complex wherein the enzyme is immobilized and yet the carbon retains its surface activity. Preferred immobilizing agents are quaternary ammonium forms of aminocarbodiimides or hydrochloric acid salts of water-soluble carbodiimides. The immobilization of the enzymes on activated carbon provides materials which are easily handled and which are stabilized against denaturation by hydrogen peroxide.

    摘要: The present invention relates to genetic-engineering of plants for enhanced oxygen assimilation and utilization. More particularly, this invention relates to producing transgenic plants engineered to express oxygen-binding proteins such as, for example, hemoglobin, myoglobin, and hemoproteins. The engineered plants of the invention achieve quicker germination, are faster growing or maturing crops, produce higher crop yields, and/or contain higher levels of desired plant metabolites, particularly alkaloids.

    摘要: In a scale model of a lowrider vehicle including a chassis and first and second spaced axles supported on the chassis, a lift assembly includes the chassis being provided with guide structure for maintaining the transverse orientation of the first axle while allowing movement of the axle relative to the chassis within a plane perpendicular to the central longitudinal axis of the chassis. A lifting assembly is provided on the chassis for lifting the chassis relative to the axle between a lowered position and a raised position so as to simulate lifting and lowering movements of the modeled lowrider vehicle. In this manner, it is possible to simulate front and back, side-to-side and hopping moves conventionally performed with actual lowrider vehicles.

    摘要: The invention relates to nucleotide sequences, including a substantially purified gene which codes for an oxygen-binding protein, and a gene promoter/regulator which is useful in subjecting the translation/transcription of DNA sequences to selective regulation by external control, and plasmid vectors containing those nucleotide sequences, which are valuable bioprocessing catalysts for enhancing the growth characteristics of cells, and increasing production of various proteins and metabolites of those cells. Methods for the use of these nucleotide sequences and related plasmids for a range of applications including oxygen supply to cells, growth enhancement, expression of various gene products, enhancement of oxygen-requiring processes, binding and separation of oxygen from liquids and gases, and a range of oxidative reactions are also disclosed.

    摘要: Recombinant cells providing for the controlled expression of product proteins by way of cross-regulation between interacting operons. A structural gene for a product protein and a structural gene for a repressor of a second operon are included in a first operon. A protein encoded by a structural gene of the second operon is a repressor of the first operon. The second operon may reside on a plasmid or a chromosome of the host cell. The present invention provides for controlled expression of product protein over a range of copy numbers, as well as high transcription efficiency in the induced state. The invention includes methods for the controlled expression of product protein by recombinant cells.
