   3.4.21.1 | 1,2-propanediol |
residual activity of bovine pancreatic alpha-chymotrypsin is studied in water/1,2-propanediol mixtures in the entire range of water content at 25°C. The degree of stabilization/ destabilization of alpha-chymotrypsin depends strongly on the water content in organic solvent. At high water content, the residual activity values are higher than 100%. At low water content, the residual catalytic activity is about 90-95%, compared with that observed after incubation in pure water |

| 3.4.21.1 | 1,8-bis(tributylammonium)octane dibromide |
provokes superactivation and stabilization effects in a way similar to cetyltributytetrabutylammonium bromide, but at lower concentration |
755380 |
| 3.4.21.1 | benzyldodecyldimethylammonium bromide |
increases activity instantaneously, but a deactivates the enzyme, faster than in pure buffer |
755380 |
| 3.4.21.1 | benzyltributylammonium bromide |
increases activity instantaneously, but a deactivates the enzyme, faster than in pure buffer |
755380 |
| 3.4.21.1 | benzyltrimethylammonium bromide |
increases activity instantaneously, but a deactivates the enzyme, faster than in pure buffer |

| 3.4.21.1 | cetyltributylammonium bromide |
promotes activity |

| 3.4.21.1 | cetyltributylammonium bromide |
provokes a superactivation of alpha-chymotrypsin in aqueous solution |

| 3.4.21.1 | dodecyltrimethylammonium bromide |
2-20 mM |
669634 |
| 3.4.21.1 | dodecyltrimethylammonium bromide |
in comparison to buffer the catalytic activity of the enzyme is enhanced 5fold in premicellar dodecyltrimethylammonium bromide solutions. Negligible changes are observed in cetyltrimethylammonium bromide and octadecyltrimethylammonium bromide |
