  • Patent number: 7943351
    Abstract: The present invention relates to a method for acyltransferase reaction in which an acyl group of acyl coenzyme A is transferred to an acyl group receptor characterized in that the reaction is carried out by production and/or reproduction of acyl coenzyme A from coenzyme A in a reaction system by a chemical thioester exchange reaction with acylthioester. The present invention, wherein expensive acyl CoA is reproduced nonenzymatically in a reaction system, enables to continuously carry out acyltransferase reaction only by putting a small amount of acyl CoA with a donor and a receptor of an acyl group into a system. Accordingly, the method of the present invention can be applied to an industrial production method of various kinds of compounds including useful biological molecules and synthesis of polymers such as polyester.

  • Publication number: 20050214374
    Abstract: The artificial extracellular matrix of the present invention comprises heat stable fish collagen produced from fish collagen with a heat denaturation temperature lower than 37° C. by improving its heat stability. The artificial extracellular matrix of the invention has an adequate stability in living bodies and a function to activate tissue repair at a high level and requires no addition of heat denatured collagen. In addition, the artificial extracellular matrix is unlikely to contain pathogenic organisms because it uses collagen originated from fish.
