Cryo-EM structure of the yeast Saccharomyces cerevisiae SDH provides a template for eco-friendly fungicide discovery

Nature Communications
Succinate dehydrogenase (SDH) is a key fungicidal target, but rational inhibitors design has been impeded by the lack of fungal SDH structure. Here, we show the cryo-EM structure of SDH from Saccharomyces cerevisiae (ScSDH) in apo (3.36 Å) and ubiquinone-
