they were strongly inhibited by thiol proteinase inhibitors , such as p-chloromercuribenzoate ( pcmb ) , p-chloromercuriphenyl sulfonate ( pcmps ) , and n- [ n- ( l-3-trans-carboxyoxirane-2-carbonyl ) -l-leucyl ] agmatine ( e-64 ) , whereas pepstatin , diisopropylphosphorofluoridate , and edta were without effect , suggesting that they are thiol enzymes .
