O substrato utilizado para a quimiotripsina foi 1mM BTEE ([micro]-benzoyl-Ltyrosineethylester) em metanol 2:3 (v/v), ensaiada em Ca[Cl.sub.2] 0,1M e Tris-HCl 0,1M (pH 7,8) a 25[degrees]C, durante 60s a 256nm.
Hydrolysis levels of peptide and protein contained in leaf skin AP-CPase were also evaluated in the same manner using dipeptide, tetrapeptide, bradykinin, casein, [alpha]-N-benzayl-DL-arginine-p-nitroanilide (BApNA), N-acetyl-L-tyrosine ethyl ester (ATEE) and N-benzoyl-L-Tyr-ethyl-ester (BTEE).
Chymotrypsin activity (EC 3.4.21.1) was measured according to continuous method reported by Hummel (1959), and previously used on crabs (Galgani & Nagayama, 1986), using 630 [micro]L BTEE (0.56 mM N-benzoyl-L-tyrosine-ethyl ester) dissolved in a buffer of 0.12 M Tris-HCl with 20 mM CaC[l.sub.2] pH 8.1 as substrate, 70 [micro]L of gastric juices and absorbance of reaction products on final volume reaction (700 [micro]L) was measured at 256 nm.
