ABSTRACT
Ovomucoid from the egg white of turtle-dove (Streptopelia risoria) was purified and shown to be a glycoprotein of mol. wt. 29 400, with valine as N-terminal residue. It is an inhibitor of both trypsin and chymotrypsin, but has a lower affinity for trypsin than has hen ovomucoid. Turtle-dove ovomucoid contains antigenic activity cross-reacting with the blood-group-P1 antigen of human erythrocytes. Hen ovomucoid has no detectable blood group-P1 activity. The carbohydrate composition of turtle-dove ovomucoid differs from hen ovomucoid in having substantially higher galactose content. The possible relationship between carbohydrate composition and antigenic activity is discussed.
