CA   (1) beta-alanyl-L-lysine + H2O = beta-alanine + L-lysine.
CA   (2) beta-alanyl-L-ornithine + H2O = beta-alanine + L-ornithine.
CA   (3) beta-alanyl-L-arginine + H2O = beta-alanine + L-arginine.
CA   (4) H2O + N(2)-(4-aminobutanoyl)-L-lysine = 4-aminobutanoate + L-lysine.
CA   (5) H2O + N(2)-(4-aminobutanoyl)-L-ornithine = 4-aminobutanoate +
