3.4.25.1 | Ca2+ |
significantly stimulates activity of the 20S proteasome at pH 7.5, completely inhibits at pH 5.5 |
670038 |
3.4.25.1 | Ca2+ |
stimulates chymotrypsin-like activity |
137329, 137338, 137345 |
3.4.25.1 | 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) |
