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.
