Abstract:
According to the present invention, a coenzyme A-dependent succinate semialdehyde dehydrogenase (SUCD) expresses microorganisms on vectors wherein the microorganisms are allowed to efficiently produce a C4 compound, so various C4 compounds can be produced by using modified genes of the microorganism. In addition, producing the C4 compound by the microorganism has an outstanding productivity, so the microorganism is industrially highly applicable.
Abstract:
Provided are a novel promoter of Corynebacterium glutamicum; a vector including the promoter; a host cell having the vector; and a method to express gene using the host cell. When comparing and analyzing the expression of the promoter with a conventional gapA promoter, high expression level is maintained not only under an aerobic condition but an anaerobic condition. Construction of a system which can overexpress desired genes in the Corynebacterium glutamicum using the promoter can be possible.
Abstract:
The present invention relates to an electronic device authenticating a user by using an access point and surrounding devices and a method for the same. The operation method for the electronic device includes a step of determining whether the electronic device is connected to at least one among a stored access point and a stored device within a predetermined time and a step of requesting user authentication which is set if the device is not connected to at least one among the stored access point and the stored device within the predetermined time. [Reference numerals] (AA) Stored access point list; (BB) Access point 1; (CC) Access point 2; (DD) Access point 3; (EE) Stored device list; (FF) Device 1; (GG) Device 2; (HH) Device 3; (II) User authentication
