Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
physiological function
enzymatic degradation of protein aggregates by pernisine, such as for infective prions (PrPSc) from different origins (i.e., mouse, bovine, deer, human)
additional information
pernisine is a subtilisin-like serine protease (i.e., a subtilase) with the catalytic triad of Asp149, His184 and Ser355. Catalytic nucleophile Ser355 has an important role in pernisine activity, but not in its activation process
additional information
prepro-Tk-subtilisin (Prepro-TKS), which consists of the signal sequence [Met (-24)-Ala(-1)], propeptide (Tkpro, Gly1-Leu69), and mature domain (Tk-subtilisin, Gly70-Gly398). the pro-enzyme form contains the insertion sequence, IS1, at the N-terminus of the mature domain which is required not only for hyperstabilization of Pro-TKS but also for its rapid maturation
