Amphinase

Amphinase is a ribonuclease enzyme found in the oocytes of the Northern leopard frog (Rana pipiens). Amphinase is a member of the pancreatic ribonuclease protein superfamily and degrades long RNA substrates.[2] Along with ranpirnase, another leopard frog ribonuclease, amphinase has been studied as a potential cancer therapy due to its unusual mechanism of cytotoxicity tested against tumor cells.[3]
