Abstract
A simple spin system is studied as an analog for proteins, We investigate h ow the introduction of randomness and frustration into the system affects t he designability and stability of ground-state configurations. We observe t hat the spin system exhibits proteinlike behavior in the vicinity of the tr ansition between a ferromagnet and a spin glass. Our results illuminate som e guiding principles in protein evolution.
