Electrophoretically distinct formls of the enzyme or enzymes which catalyze the hydrolysis of L-leucyl-beta-naphthylamide were demonstrated in various human tissues. There were characteristic patterns for different tissues. Unlike the enzymes found in normnal serum, some tissue-specific enzymes were unaffected or activated L-methionine.
