1. This dimerization has no effect on the catalytic activity of the enzyme. 2. The nitro variant has different solubility and catalytic activity in some reactions. 3. So far, all catalytic antibodies produced have displayed only modest, weak catalytic activity . 4. The B regulatory subunit might modulate substrate selectivity and catalytic activity . 5. PTPmu has a long juxtamembrane domain, which likely influences catalytic activity . 6. The reasons for low catalytic activity for these molecules have been widely discussed. 7. In particular, they use transition metals and various nucleophilic mechanisms for catalytic activity . 8. In the absence of acetate, there is almost no catalytic activity . 9. CAB39 enhances formation of STK11 / STRAD complexes and stimulates STK11 catalytic activity . 10. Corin exhibits a trypsin-like catalytic activity favoring basic residues at the P1 position.
