abstract：:We present sequences of five novel RNase A superfamily ribonuclease genes of the bullfrog, Rana catesbeiana. All five genes encode ribonucleases that are similar to Onconase, a cytotoxic ribonuclease isolated from oocytes of R. pipiens. With amino acid sequence data from 14 ribonucleases from three Rana species (R. ca...
