Abstract
A new acidic glycoprotein containing deaminated neuraminic acid (KDN = 3-deoxy-D-glycero-D-galacto-nonulosonic acid; greater than 50%, w/w) was isolated from vitelline envelope of the unfertilized eggs of rainbow trout (Salmo gairdneri). This glycoprotein is designated as "KDN-glycoprotein" because it contains only KDN but no sialic acid as the acidic carbohydrate moieties. Other major carbohydrate components of KDN-glycoprotein were Gal and GalNAc. Thr and Ala accounted for 71% (mol/mol) of amino acid composition. A possible occurrence of KDN-KDN linkages, i.e. oligoKDN groups has been suggested in the carbohydrate chains presumably linked O-glycosidically to the core protein.Entities:
