LITERATURE
medicine
single nucleotide polymorphisms ALG6 rs10889417 G>A and GALNTL4 rs12270446 G>C independently predict cutaneous melanoma disease-specific survival. The low death-risk-associated rs10889417 A allele is associated with increase in ALG6 mRNA expression levels in cultured skin fibroblasts and whole blood cells and the rs12270446 G allele is associated with decrease in GALNTL4 mRNA expression levels in skin tissues
synthesis

genetic engineering of N-glycan biosynthesis in Yarrowia lipolytica so that it produces Man(3)GlcNAc(2) structures on its glycoproteins. Disruption of the ALG3 gene, EC 2.4.1.258, results in modification of proteins mainly with Man(5)GlcNAc(2) and GlcMan(5)GlcNAc(2) glycans, and to a lesser extent with Glc(2)Man(5)GlcNAc(2) glycans. To avoid underoccupancy of glycosylation sites, Alg6, EC 2.4.1.267, is concomitantly overexpressed. Overexpression of the heterodimeric Aspergillus niger glucosidase II results in removal the terminal glucose residues. Overexpression of an alpha-1,2-mannosidase leads to Man(3)GlcNAc(2) structures, which are substrates for the synthesis of complex-type glycans. The final Yarrowia lipolytica strain produces proteins glycosylated with the trimannosyl core N-glycan (Man(3)GlcNAc(2)), which is the common core of all complex-type N-glycans
