描述
alpha-D-Manp-(1->2)-alpha-D-Manp-(1->2)-alpha-D-Manp-(1->3)-beta-D-Manp-(1->4)-D-GlcNAcp is a pentasaccharide found in the urine of patients with mannosidosis (PMID: 953057). It is a glycan structure of human milk glycoprotein glycopeptides (PMID: 6698017). This oligosaccharide is derived from high-mannose and different complex and hybrid asparagine-linked glycans and from the storage products in alpha-mannosidosis. The human liver lysosomal alpha-mannosidase (EC 3.2.1.24) enzyme that specifically hydrolyzes all alpha(1-2)-, alpha(1-3)- and alpha(1-6)-mannosidic linkages in these glycans. (PMID: 1872811) [HMDB]
