O-acetylation and de-O-acetylation of sialic acids. 7- and 9-o-acetylation of alpha 2,6-linked sialic acids on endogenous N-linked glycans in rat liver Golgi vesicles.
Diaz S, Higa HH, Hayes BK, Varki A. Diaz S, et al. Among authors: varki a. J Biol Chem. 1989 Nov 15;264(32):19416-26. J Biol Chem. 1989. PMID: 2808433 Free article.
The incorporated radioactivity occurred in acid-soluble and acid-insoluble components, and the acid-insoluble fraction included O-acetylated sialic acids (Varki, A., and Diaz, S. (1985) J. Biol. Chem. 260, 6600-6608). Nearly all of the protein-associated radioactivi …

Sulfated N-linked oligosaccharides in mammalian cells. I. Complex-type chains with sialic acids and O-sulfate esters.
Roux L, Holojda S, Sundblad G, Freeze HH, Varki A. Roux L, et al. Among authors: varki a. J Biol Chem. 1988 Jun 25;263(18):8879-89. J Biol Chem. 1988. PMID: 3379050 Free article.
H., and Varki, A. (1986) Biochem. Biophys. Res. Commun. 140, 967-973). Here we report improved methods to metabolically label cell lines with 35SO4 and to release sulfated N-linked oligosaccharides with peptide:N-glycosidase F as well as the partial structure of som …

Endothelial heparan sulfate proteoglycans that bind to L-selectin have glucosamine residues with unsubstituted amino groups.
Norgard-Sumnicht K, Varki A. Norgard-Sumnicht K, et al. Among authors: varki a. J Biol Chem. 1995 May 19;270(20):12012-24. doi: 10.1074/jbc.270.20.12012. J Biol Chem. 1995. PMID: 7538130 Free article.
We earlier reported calcium-dependent, heparin-like L-selectin ligands in cultured bovine endothelial cells (Norgard-Sumnicht, K. E., Varki, N. M., and Varki, A. (1993) Science 261,480-483). Here we show that these are heparan sulfate proteoglycans (HSPGs) as …
