Research highlights

Reactivity derails PKS prediction Polyketide synthases (PKSs) are multidomain proteins in which eachdomain performs a specific type of chemistry on the way to a polyketide product. Because the domains are highly conserved, it is often possible to predict not only the reaction performed by each domain but also the preferred substrate.
