  • Patent number: 8476051
    Abstract: An alcohol dehydrogenase (ADH) from hyperthermophilic archaeon Thermococcus guaymasensis was purified to homogeneity and was found to be a homotetramer with a subunit size of 40±1 kDa. The gene encoding the enzyme was cloned and sequenced, and found to have significant sequence homology to known zinc-containing ADHs and L-threonine dehydrogenases with both binding motifs of catalytic zinc and NADP+. The wild-type enzyme is a primary-secondary ADH that exhibits a substrate preference for secondary alcohols and corresponding ketones, and exhibits unusual stereoselectivity. The wild-type enzyme was found to have outstanding thermostability, demonstrating 60% activity after incubation at 80° C. for 40 hours. Site-directed mutagenesis was used to substitute the cyteine residue at position 56 with a serine, to provide the TgADH(C56S) mutant. In the assays that we carried out, we found virtually no difference in enzyme activity and oxygen-sensitivity between the mutant TgADH (C56S) and wild type TgADH.

  • Publication number: 20130143130
    Abstract: Disclosed is a composite of enzyme and carbon structure. In the composite of enzyme and carbon structure, a significantly large amount of an enzymeis immobilized on the surface of carbon structures without the formation of chemical bonds (particularly, covalent bonds) between the enzyme molecules and the carbon structures. Since the surface of the carbon structures does not need to be modified to form chemical bonds, the electrical conductivity of the composite of enzyme and carbon structure is not reduced and the stability of the composite is maintained high even after the passage of a long time in various environments. Therefore, the use of the composite of enzyme and carbon structure enables the fabrication of various devices, such as biosensors and biofuel cells, with markedly improved performance as compared to the use of conventional enzyme/carbon structure composites.

    Abstract: A process is provided for producing peroxycarboxylic acids from carboxylic acid esters. More specifically, carboxylic acid esters are reacted with an inorganic peroxide, such as hydrogen peroxide, in the presence of an enzyme catalyst having perhydrolysis activity. The present perhydrolase catalysts are classified as members of the carbohydrate esterase family 7 (CE-7) based on the conserved structural features. Further, disinfectant formulations comprising the peracids produced by the processes described herein are provided.

  • Publication number: 20120309072
    Abstract: The present invention relates to a method for purifying target protein which contains electron transfer protein, from a protein solution containing the target protein, by means of liquid chromatography. The liquid chromatography is performed as follows: First, the protein solution is introduced into a column which is filled with a packing agent, thereby causing the packing agent to bond to the target protein. Then, impurities are removed, and then the target protein is eluted from the packing agent in an eluent which contains a hydroxy-cholate. An example of the target protein is glucose dehydrogenase which contains a protein having glucose dehydrogenation activity. The liquid chromatography is performed as a combination of hydrophobic chromatography and anion exchange chromatography.
