http://purl.uniprot.org/citations/15893436http://www.w3.org/2000/01/rdf-schema#comment"In this work we identify an intronless open reading frame encoding an RNase A ribonuclease from genomic DNA from the Iguana iguana IgH2 cell line. The iguana RNase is expressed primarily in pancreas, and represents the majority of the specific enzymatic activity in this tissue. The encoded sequence shares many features with its better-known mammalian counterparts including the crucial His12, Lys40 and His114 catalytic residues and efficient hydrolytic activity against yeast tRNA substrate (k(cat)/K(m)=6 x 10(4) M(-1) s(-1)), albeit at a reduced pH optimum (pH 6.0). Although the catalytic activity of the iguana RNase is not diminished by human placental RI, iguana RNase is not bactericidal nor is it cytotoxic even at micromolar concentrations. Phylogenetic analysis indicates moderate (46%) amino acid sequence similarity to a pancreatic RNase isolated from Chelydra serpentina (snapping turtle) although no specific relationship could be determined between these RNases and the pancreatic ribonucleases characterized among mammalian species. Further analysis of ribonucleases from non-mammalian vertebrate species is needed in order to define relationships and lineages within the larger RNase A gene superfamily."xsd:string
