Glucosamine 155-166 glypican 1 Homo sapiens 26-36 9061369-1 1997 Skin fibroblasts treated with brefeldin A produce a recycling variant of glypican (a glycosylphosphatidylinositolanchored heparan-sulfate proteoglycan) that is resistant to inositol-specific phospholipase C and incorporates sulfate and glucosamine into heparan sulfate chains (Fransson, L.-A. Glucosamine 236-247 glypican 1 Homo sapiens 73-81 19479373-9 2009 We also show that the N-unsubstituted glucosamine residues are formed during biosynthesis of glypican-1 and that the content increased upon inhibition of polyamine synthesis. Glucosamine 38-49 glypican 1 Homo sapiens 93-103 19479373-2 2009 Cell surface-bound glypican-1 becomes internalized and recycles via endosomes, where the heparan sulphate chains undergo nitric oxide and copper dependent autocleavage at N-unsubstituted glucosamines, back to the Golgi. Glucosamine 187-199 glypican 1 Homo sapiens 19-29 16971378-1 2006 The recycling heparan sulfate (HS)-containing proteoglycan glypican-1 (Gpc-1) is processed by nitric oxide (NO)-catalyzed deaminative cleavage of its HS chains at N-unsubstituted glucosamines. Glucosamine 179-191 glypican 1 Homo sapiens 59-69 16971378-1 2006 The recycling heparan sulfate (HS)-containing proteoglycan glypican-1 (Gpc-1) is processed by nitric oxide (NO)-catalyzed deaminative cleavage of its HS chains at N-unsubstituted glucosamines. Glucosamine 179-191 glypican 1 Homo sapiens 71-76 15112050-5 2004 When glypican-1 is exposed to ascorbate, nitric oxide is released and participates in deaminative cleavage of heparan sulfate at sites where the glucosamines have a free amino group. Glucosamine 145-157 glypican 1 Homo sapiens 5-15 12479862-7 2003 The glypican-1 core protein is S-nitrosylated and nitric oxide released from these sites cleave the HS chains at glucosamine units lacking N-substitution. Glucosamine 113-124 glypican 1 Homo sapiens 4-14 10814699-8 2000 We propose that, in recycling glypican-1, heparan sulfate chains are cleaved at or near glucosamines with unsubstituted amino groups. Glucosamine 88-100 glypican 1 Homo sapiens 30-40 11110783-0 2001 N-unsubstituted glucosamine in heparan sulfate of recycling glypican-1 from suramin-treated and nitrite-deprived endothelial cells. Glucosamine 16-27 glypican 1 Homo sapiens 60-70 11110783-2 2001 We have analyzed the content of N-unsubstituted glucosamine in heparan sulfate from glypican-1 synthesized by endothelial cells during inhibition of (a) intracellular progression by brefeldin A, (b) heparan sulfate degradation by suramin, and/or (c) endogenous nitrite formation. Glucosamine 48-59 glypican 1 Homo sapiens 84-94 11110783-3 2001 Glypican-1 from brefeldin A-treated cells carried heparan sulfate chains that were extensively degraded by nitrous acid at pH 3.9, indicating the presence of glucosamines with free amino groups.
