1 N - Glycan structures of pigeon IgG : a major serum glycoprotein containing Gal 1 - 4 Gal termini

Structural analysis of N-glycans from gull egg white glycoproteins and egg yolk IgG.

We previously showed that the expression of (Gal alpha 1-4Gal)-bearing glycoproteins among birds is related to their phylogeny. However, precise structures of (Gal alpha 1-4Gal)-containing N-glycans were only known for pigeon egg white glycoproteins and IgG. To compare structural features of (Gal alpha 1-4Gal)-containing N-glycans from other species, we analyzed N-glycans of gull egg white (GEW...

N-Glycan structures from the major glycoproteins of pigeon egg white: Predominance of terminal Galα(1-4)Gal

The carbohydrate-binding domain on galectin-1 is more extensive for a complex glycan than for simple saccharides: implications for galectin–glycan interactions at the cell surface

gal-1 (galectin-1) mediates cell-cell and cell-extracellular matrix adhesion, essentially by interacting with beta-galactoside-containing glycans of cell-surface glycoconjugates. Although most structural studies with gal-1 have investigated its binding to simple carbohydrates, in particular lactose and N-acetyl-lactosamine, this view is limited, because gal-1 functions at the cell surface by in...

N-glycan structures from the major glycoproteins of pigeon egg white: predominance of terminal Galalpha(1)Gal.

N-Glycans from major glycoproteins of pigeon egg white (ovotransferrin, ovomucoid, and ovalbumins) were enzymatically released and were reductively aminated with 2-aminopyridine, separated, and structurally characterized by mass spectrometry and a three-dimensional mapping technique using three different columns of high performance liquid chromatography (HPLC) (Takahashi, N., Nakagawa, H., Fuji...

Structural studies of a novel type of pentaantennary large glycan unit in the fertilization-associated carbohydrate-rich glycopeptide isolated from the fertilized eggs of Oryzias latipes.

In a previous report (Kitajima, K., Inoue, S., and Inoue, Y. (1989) Dev. Biol. 132, 544-553), we found the presence of a heavily glycosylated polyprotein, "H-hyosophorin," isolated from the unfertilized eggs of Oryzias latipes. We now report our detailed analysis of the structure of the N-glycan chain in L-hyosophorin, the smallest repeating unit of H-hyosophorin, which was isolated from the fe...
