The Trypsin-Chymotrypsin mixture is the co-crystal of chymotrypsin and trypsin, so it has both properties.
The activity of both hydrolysing casein is as much as chymotrypsin. But the activity of its chymotrypsin to hydrolyse N-benzoyl-L-tyrosine ethyl ester (Btee) is three times higher than chymotrypsin. The activity of hydrolysing ester bonds is similar to that of trypsin.
It is stable when dry and easy to be inactivated in solutions.
In the clinical field, it’s used for anti-inflammatory drugs.
