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. WebPlant proteases play a crucial role in many different biological processes along the plant life cycle. One of the most determinant stages in which proteases are key protagonists is the plant germination through the hydrolysis and mobilization of other proteins accumulated in seeds and cereal grains. The most represented proteases in charge of this are the …
