Abstract

One of the two ribonuclease genes in a leaf-eating monkey has adapted to a role in the digestion of bacterial RNA. Following duplication of the ancestral ribonuclease gene, adaptation occurred through a series of changes in the amino acid sequence of the protein it encodes. This example is a good illustration of how specialization of protein function after gene duplication can be as source of novel protein functions.
