Which plant genus has more known species, Nepenthes or Anoda?
Anoda Anoda is a genus of flowering plants in the mallow family. There are 23 or 24 species of these herbs, most native to Mexico and South America. They are generally erect plants with a variety of leaf shapes, and many bear colorful flowers. Most bear distinctive disk-shaped segmented fruits.
Nepenthesin Nepenthesin (also spelled nepenthacin or nepenthasin) is an aspartic protease of plant origin that has so far been identified in the pitcher secretions of "Nepenthes" and in the leaves of "Drosera peltata". It is similar to pepsin, but differs in that it also cleaves on either side of Asp residues and at Lys┼Arg. While more pH and temperature stable than porcine pepsin A, it is considerably less stable in urea or guanidine hydrochloride. It is the only known protein with such a stability profile.
