mercapto protease

2005, "Proceedings on Rose Breeding, Cultivation and Production in China", Y Lin, Q Liu, IV International Symposium on Rose Research and Cultivation, actahort.org Mercapto-protease and serine protease were both found in rose petals.

The protease may be mercapto protease, preferably papain.

2020, "Electrochemical detection of silver ions by using sulfur quantum dots modified gold electrode", L Fu, A Wang, K Xie, J Zhu, F Chen, H Wang, et al., Sensors and Actuators B: Chemical, Elsevier The principle is that silver ion can inhibit the activity of free mercapto protease and thus inhibit its biological function [[4], [5], [6]].

2021, "Cloning, expression and characterization of metalloproteinase HypZn from Aspergillus niger", P Song, W Xu, K Wang, Y Zhang, F Wang, X Zhou, et al., PLoS one, journals.plos.org The cysteine protease inhibitor E-64 had little effect on enzyme activity, indicating that the HypZn active site does not contain cysteine and that it is not a mercaptoprotease.
