Ipomoea batatas: papain propeptide inhibits cysteine protease in main plant parasites and enhances resistance of transgenic tomato to parasites.

ABSTRACT: Different parasites cause severe lose in quantity and quality of crops. Many parasites develop haustorial cells and stylets that penetrate the host using secreted enzymes and mechanical pressure. Cysteine proteases are pre-pro-enzyme produced by parasites that are essential for normal parasitism. Papain is also a kind of cysteine proteases such that its propeptide segment has inhibitory properties and limits the protease activity of papain. To investigate the inhibitory effects of papain propeptide on some parasite proteases, we cloned inhibitory propeptide of papain of Ipomoea batatas, and enzymatic fragments of Diabrotica virgifera cathepsin L-like protease-1, Meloidogyne incognita cathepsin L-like protease 1, Heterodera glycines cysteine protease-1, Cuscut
