At low enough temperatures, any enzymatic or chemical activity which might cause damage to the material in question is effectively stopped.
A clear dose-response was observed in the levels of caspase-8 enzymatic activity.
Phospholipases A2 include several unrelated protein families with common enzymatic activity.
Typically it will have enzymatic activity inside the host cell.
This has no clear enzymatic activity, and may serve as a carrier for the A subunit.
The cell is typically chilled overnight before use to preserve enzymatic activities.
Res is required for restriction, although it has no enzymatic activity on its own.
The first seems to have enzymatic activity, whereas the second is inactive.
This enzymatic activity can be measured with high time resolution in real time.
No enzymatic activity could be demonstrated to catalyze this reaction.
