Carbohydrate in Pancreatic Ribonucleases
A survey of the presence and compositions of carbohydrate chains attached to pancreatic ribonucleases is given. Carbohydrate chains may occur at asparagine residues in Asn-X-Ser/Thr sequences at four exposed sites of the molecule (positions 21, 34, 62, and 76). These sites form part of highly variant sequences in pancreatic ribonucleases with the consequence that the […]
