CATH List Funfams

List functional families (FunFams) within a CATH superfamily. FunFams group protein domains that share the same function, identified by conserved specificity-determining residues. Returns FunFam numbers, names, member counts, and representative domain IDs. Example: superfamily 1.10.510.10 (Globin-like) has 4,524 FunFams including CaM kinase (2,698 members) and Myosin light chain kinase (1,234 members). Use CATH_get_superfamily to find superfamily IDs first.
