LITERATURE
Cd2+
-
0.3 mM Cd2+ lead to a 1.6 and 2.3fold increase in the 20S proteasome activity after 3 and 10 days, respectively, in leaves, the chymotrypsin activity of the 20S proteasome is maximally increased only after 3 days of treatment with 0.03 mM and 0.3 mM Cd2+ (1.5 and 2.5fold, respectively), no major effect of Cd2+ on the chymotrypsin activity of the 20S proteasome is observed in roots or leaves of plant treated with low Cd2+ concentrations (0.0003 mM and 0.003 mM)
Cl-
-
stimulates chymotrypsin-like activity
Mn2+
-
stimulates chymotrypsin-like activity
Na+
-
100 mM, decreases the rate of hydrolysis of succinyl-Leu-Leu-Val-Tyr-7-amido-4-methylcoumarin and succinyl-Ala-Ala-Phe-7-amido-4-methylcoumarin 2fold
PMSF
-
activates chymotrypsin-like activity
