1 Comparison of the amino acid sequences of RNase and angiogenin reveals several striking differences in the region flanking the active-site lysine, including a deletion and a transposition of aspartic acid and proline residues. Proline ribonuclease A family member k6 Gallus gallus
2 In order to examine how these sequence changes alter the functional properties of angiogenin, an angiogenin/RNase hybrid protein (ARH-II), in which residues 38-41 of angiogenin (Pro-Cys-Lys-Asp) have been replaced by the corresponding segment of bovine pancreatic RNase (Asp-Arg-Cys-Lys-Pro), was prepared by regional mutagenesis. Proline ribonuclease A family member k6 Gallus gallus
