evolution | Parapriacanthus ransonneti, a bioluminescent fish, obtains not only its luciferin but also its luciferase enzyme from bioluminescent ostracod prey. Experiments where fish are fed with Vargula hilgendorfii, demonstrate the specific uptake of the luciferase to the fish's light organs. This kleptoprotein system allows an organism to use novel functional proteins that are not encoded in its genome and provides an evolutionary alternative to DNA-based molecular evolution | Vargula hilgendorfii |
evolution | Parapriacanthus ransonneti, a bioluminescent fish, obtains not only its luciferin but also its luciferase enzyme from bioluminescent ostracod prey. The enzyme purified from the fish's light organs is identical to the luciferase of Cypridina noctiluca, a bioluminescent ostracod that they feed upon. This kleptoprotein system allows an organism to use novel functional proteins that are not encoded in its genome and provides an evolutionary alternative to DNA-based molecular evolution | Cypridina noctiluca |
