Abstract/OtherAbstract:
|
Data reported in this paper show that both lysine transport systems in E. coli KL16 can be repressed by lysine and its isologs, thialysine and selenalysine, whereas they are not repressed by ornithine. The repression is specific on lysine transport systems; it is evident with 0.01 mM lysine or isolog concentration and reaches a maximum with 0.1 mM concentration. By comparing the extent of repression by lysine and its isologs, lysine gives the highest and selenalysine the lowest degree of repression. The shift from the repressed to the depressed state is rather immediate once the amino acid is removed from the culture medium. |
