  • Patent number: 11142755
    Abstract: A mutant glutathione synthetase (GSHB) suitable for generating ?-Glu-Val-Gly, and a method for producing ?-Glu-Val-Gly using the same are provided. ?-Glu-Val-Gly is produced by using a mutant GSHB having a mutation at such a position as V7, N13, I14, N15, K17, F22, F95, M165, N199, Y200, P202, I274, T285, and P287.

  • Publication number: 20210070800
    Abstract: A method for producing ?-Glu-Val-Gly is described, wherein the method includes the steps of cultivating a ?-Glu-Val-Gly-producing bacterium belonging to the family Enterobacteriaceae in a culture medium so that the ?-Glu-Val-Gly accumulates in the culture medium or the cells of the bacterium, or both, and collecting the ?-Glu-Val-Gly from the culture medium or the cells of the bacterium, or both. The bacterium has been modified to overexpress a gene encoding a protein having L-threonine 3-dehydrogenase activity and a gene encoding a protein having 2-amino-3-oxobutanoate coenzyme A ligase activity.

  • Patent number: 5958853
    Abstract: A disinfectant and cleansing composition is provided in the form of an extruded solid. The active agent in the composition is a halogen-releasing agent such as a halogenated 5,5-dialylhydantoin. An inert binder such as a fatty acid salt or a hectoritic clay is used to enable manufacture of the composition using an extrusion process. Fragrance, colorants, and other pressure-sensitive materials may be included; fragrance and colorants are preferably incorporated in encapsulated form. Methods for manufacturing the compositions are also provided, as are methods for using the compositions in sanitizing water, particularly in disinfecting and cleansing flush toilets.
