Nucleic acid encoding a novel ribonuclease having an amino acid sequence made up of the amino acid sequence of a known ribonuclease and an N-terminal leader sequence that is at least one residue long

摘要

A nucleic acid encodes a novel RNase. The RNase has an amino acid sequence in which an amino acid sequence disclosed in U.S. Pat. No. 6,239,257 B1 is preceded by a different N-terminal residue or leader sequence.
