Cysteine endoprotease
WebMar 9, 1993 · The isoprenylation pathway requires an endoprotease that cleaves the modified protein at the isoprenylated cysteine residue. This endoprotease was readily assayed with simple tetrapeptide substrates of the type N-acetyl-S-farnesyl-L-Cys-(AFC)-Val-Ile-Met, where AFC and the tripeptide are the products of the hydrolysis. WebThe enzyme is also known as yeast KEX2 protease, proteinase yscF, prohormone-processing endoprotease, paired-basic endopeptidase, yeast cysteine proteinase F, paired-basic endopeptidase, andrenorphin-Gly-generating enzyme, endoproteinase Kex2p, gene KEX2 dibasic proteinase, Kex 2p proteinase, Kex2 endopeptidase, Kex2 …
