COMMENTARY
LITERATURE
side-chain modification
-
presence of significant amounts of glucosamine, mannose, galactose, fucose, sialic acid; the carbohydrate is primarily attached to the larger subunit, representing 28% of its weight. Two forms detected in isoelectric focusing with pI of 3.8 and 4.3. The difference is attributed to differences in sialic acid content of the two forms
side-chain modification
-
carbohydrate accounts for 17% of the weight, contains significant amounts; presence of significant amounts of glucosamine, mannose, galactose, fucose, sialic acid
side-chain modification
-
the enzyme contains seven potential N-linked glycosylation sites and a threonine/serine-rich region which is a potential site for attachment of O-linked carbohydrate
side-chain modification
-
the 83000 Da subunit contains carbohydrate
side-chain modification
-
the subunit of MW 81000-87000 Da contains carbohydrate
side-chain modification
-
sialoprotein with at least two forms, differing in sialic acid content. Sialic acid may possibly influence stability
side-chain modification
-
the 83000 Da subunit contains about 27% carbohydrate per weight, it may contain both N-linked and O-linked carbohydrate
side-chain modification
-
the 90000 Da subunit contains carbohydrate, no carbohydrate is detected in the subunits of MW 50000 Da and 30000 Da
