Enzymatic function and their evolution in different SCOP superfamilies. For the dark bars, enzymes were grouped according to their four-digit EC number and the number of SCOP superfamilies was deduced for each of these substrate specific enzymatic functions. The light bars show the histogram deduced from a compilation of three-digit EC numbers, which subsumes enzymes with the same function but different substrates
