  • Expression vector for the regulatable expression of foreign genes in prokaryotes
    Patent number: 6190906
    Abstract: The invention provides an expression vector useful in expressing foreign genes in procaryotes. The vector consists of the promotor/operator region and initiation point of translation of the mg1 operon. This combination is referred to as a regulation sequence. In order to prepare this, desired portions of the mg1 operon are cut from the genome of a cell which can utilize galactose via appropriate restriction endonucleases. This is then inserted into a DNA vector.
