Elongation of the deprotected heptasaccharide using glycosyltransferases yielded a biantennary nonasaccharide with terminal galactose residues and two undecasaccharides terminating with alpha 2,6- or alpha 2,3-linked sialic acid. The free amino group of the spacer of these...
Sialyl-Tn antigen (STn) is a short O-glycan containing a sialic acid residue 伪2,6-linked to GalNAc伪-O-Ser/Thr. The biosynthesis of STn is mediated by a s... S Julien,PA Videira,P Delannoy - 《Biomolecules》 被引量: 55发表: 2012年 ...
