Fundamental biochemistry of the early N-glycosylation pathway

<p>Oligosaccharides destined for use as N-linked glycans are synthesised on phosphorylated dolichols in the endoplasmic reticulum (ER) by a series of glycosyltransferase enzymes known as ALG proteins. Mutations in any of these synthesis enzymes can lead to severe, multisystem syndromes known a...
