... University collaborators showed that this gene is responsible for resistance. First, the researchers found that the bacterium E. coli, whichnormally is metronidazole-resistant, became sensitive to the drug when theyinserted rdxA from H. pylori into it. Second, they made resistant H. pylorisensitive again by add...High Blood Pressure Caused By Salt Retention May Be Related To Oncogenes Implicated In Cancer

They also determined that the Ndt80 protein is responsible for thesynthesis of another set of proteins, which contribute to the unique shape ofthe spore.
