| The catalytic mechanism and the active-site fold, however, are largely conserved among the protease classes. |
| Their implications for catalytic function and ligand interaction are discussed. |
| This will be done by using lead-free petrol and by fitting catalytic converters to vehicles. |
| Numerous studies suggest that the smallest multimer with full catalytic activity is a tetramer or an octamer. |
| Furthermore, the molecular arrangement of the three citrate ligands allows the possible introduction of other catalytic metal centres. |
| The catalytic enzyme is regenerated after each activation and able to react anew with additional prodrug molecules. |
