[i] The most versatile superfamilies in single-domain proteins as determined from their functional description in SWISS-PROT, with some representatives. The keyword combinations in the fourth column were based either on the first three components of their EC numbers (for enzymes) or derived automatically by comparing the DE description line of SWISS-PROT entries to a list of synonymous keywords athttp://bioinfo.mbb.yale.edu/partslist/func. A keyword number starting with a D indicates an enzyme that does not have an assigned EC number in its description in SWISS-PROT.
