Fig. 1 gives an overview of reaction mechanism of the cysteine protease mediated cleavage of a peptide bond. The catalytic site of CA-clan papain-like cysteine proteases consists of Cys, histidine (His) and Asp residues and is highly conserved among members of the enzyme family [3]. Till ...
which are present in lysosomes, but can also be localized in extracellular spaces [7]. In mites and insect species belonging to the orders Coleoptera, Hemiptera and Homoptera most C1A peptidases, particularly cathepsins L and B-like, are involved in the digestion process [8–10]. Besides, th...

We found five inhibitors using virtual screening, and the results indicate that these drugs had the highest energy binding potential towards the EcpA targets when compared to the reference molecule E-64, a known cysteine protease inhibitor. In order to evaluate the binding conformational stability of...
sustained free drug levels to achieve efficacious inhibition.1,5,6In this way, systemic drug levels can be lowered to enhance safety margins (an effect that has been suggested for the BTK inhibitoribrutinib, for example).7 Although the low frequency of cysteine enables the development of ...

Squamous cell carcinomas (SCC) were experimentally produced in hairless mouse skin, and cysteine protease and its inhibitor were simultaneously purified from extracts of 1 g of tissue of SCC and normal skin. Activity of cysteine proteinases, M r > 50,000 and M r 28,000, increased in SCC co...
All barley cystatins, except HvCPI-1 and HvCPI-7, inhibited in vitro mite cathepsin L- and/or cathepsin B-like activities, HvCPI-6 being the strongest inhibitor for both mite species. Transgenic maize plants expressing HvCPI-6 protein were generated and the functional integrity of the ...
