De novo protein design proceeds in two steps: first, the generation of target protein backbones, and second, the design of sequences whose lowest energy states are the target backbones. Since its inception, it has been used to reproduce a plethora of reactions and uncover biophysical principles that are often difficult to extract from direct studies of natural proteins. A paucity of structures meant that a disproportionate amount of work over the last decade in membrane protein design has been performed using de novo approaches.De novo proteins are traditionally designed using two distinct methodsminimal and rational.
