structure determination of bacterial dehydroquinase type II and shikimate kinase - inhibitor complexes

In collaboration with the group of Concepción González-Bello (CIQUS, University of Santiago de Compostela)

The shikimic acid pathway is essential to many pathogens but absent in mammals. Enzymes in its pathway are therefore appropriate targets for the development of novel antibiotics.
