Scientists unlock indole in soil bacteria to create prodrugs
Researchers from Bochum and Leipzig have successfully used a soil bacterium to specifically produce prodrugs. The key to this step was a detailed understanding of the metabolisation of indole, a natural compound which first must be activated in microorganisms. To do this, they needed a monooxygenase, the molecular structure of ...
