 | | To develop the "humanized" mouse that would be vulnerable to bacterial streptokinase, Sun attached the gene for human plasminogen to a regulatory DNA sequence that normally activates the gene for a mouse blood protein, albumin. |
 | | In further experiments, the researchers found that when they removed the streptokinase gene from group A streptococci bacteria, there was little difference in their infectivity between normal and the transgenic mice. |
 | | Streptokinase's importance to group A streptococci may generalize to many other human-specific bacteria that have evolved their own distinctive plasminogen-activating enzymes, said Ginsburg. |
