Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.01Å Ligands: BMA, MAN, NAG Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function OCH1_YEAST Mannosyltransferase involved in outer chain elongation of asparagine-linked oligosaccharides of the type Man(9)GlcNAc(2). Adds the first alpha-1,6-mannose to the Man(8)GlcNAc(2) and Man(9)GlcNAc(2), but not Man(5)GlcNAc(2), endoplasmic reticulum intermediates. Represents the first enzymatic event required for synthesis of outer chain mannose linkages on yeast secretory proteins. Also has the potential to transfer a second alpha-1,6-mannose to the Man(8)GlcNAc(2) core oligosaccharide.
