These graphs in sequence space are connected by point mutations and centered around prototype sequences, which tolerate the largest number (up to 55%) of neutral mutations. ...
Applied to biopolymers, this implies that residues that are essential for function will be conserved, and others replaced in evolutionary diverse sequences. ...
