Evolving biosynthetic tangos negotiate mechanistic landscapes
&
Abstract
The dependence of polyketide synthase and terpene cyclase mechanistic adaptation on the chemistry of their oligomeric substrates illuminates a convergent evolutionary strategy for shaping cyclization in these otherwise disparate reactions. Evolution of these enzyme families relies on rhythmic tangos, in which the enzymes and substrates together determine product outcome by negotiating decision networks governing intrinsic and induced chemical reactivities.
