Theory for protein mutability and biogenesis.

Abstract excerpt

Using an elementary physical model for protein folding, of self-avoiding short copolymer chains on two-dimensional square lattices, we address two questions regarding the evolution and origins of globular proteins. (i) How will protein native structures and stabilities be affected by single-and double-site mutations? (ii) What is the probability that a randomly chosen sequence of amino acids will be compact and...
