  • COMPUTER SYSTEM AND USER MANAGEMENT METHOD
    Publication number: 20230394126
    Abstract: In a computer system, a tenant administrator performs user registration into and a login to a purchase manager, and then makes a request to purchase a tenant. Registered user information is stored into a marketplace user manager. An E2EO unit creates a tenant and then creates, for each tenant, a tenant user manager structured to authenticate and authorize a general user of a service. When a user who has performed the user registration into the purchase manager uses the service of the tenant, the tenant user manager delegates processing to the marketplace user manager.

  • METHOD OF PRODUCING A TRIPEPTIDE GAMMA-GLU-VAL-GLY USING ENTEROBACTERIACEAE
    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.
