Phytophthora infestans is the causal agent of late blight disease, which affects potato and tomato crops, causing significant economic losses in the production of these crops worldwide. Glucokinase 1 from P. infestans (PiGlcK-1) is a key enzyme in the metabolism of this phytopathogen. In this project we propose to make a structural characterization of PiGlck-1, which could contribute to the design of inhibitors for this enzyme that help to combat this disease.
