The light chain of the toxin has protease activity.

To achieve this goal, specific protease activity is incorporated to confer self-removing behaviour onto an epitope tag.

It is suggested that the role of cellulosome-associated serpins may be to prevent unwanted protease activity against the cellulosome.

The protein belongs to the plasminogen subfamily of S1 peptidases but has no detectable protease activity.

A study published in 2007 tested P. minensis for protease activity, a typical test for the carnivorous syndrome, and could detect none.

The encoded protein is a serum calcium-decreasing factor that has chymotrypsin-like protease activity.

This may be an important method of regulation of protease activity.

Alternatively, granzyme activity can be assayed by virtue of their protease activity.

There is also evidence of protease activity and absorption of nutrients.

A low but significant protease activity is in the venom, although there does not seem to be any hemolytic activity.
