GDP-mannose + alpha-1,6-D-mannobiose | two distinct Mnn9p-containing multi-protein complexes add multiple mannosyl residues forming a series of poly-mannose structures in vitro, no substrate of Och1p | Saccharomyces cerevisiae | ? | formation of a series of poly-mannose structures, which contain mainly alpha-1,6- and some additional alpha-1,2-linked mannoses | ? | |
GDP-mannose + oligosaccharide acceptor | Mnn9p is associated in two distinct multi-protein complexes, both having alpha-1,6-mannosyltransferase activity, they add multiple mannosyl residues forming hypermannose structures, Och1p adds the initiating alpha-1,6-mannose residue to an N-linked Man8GlcNAc2 structure, the Mnn9p-containing protein complexes add further alpha-1,6-mannose residues synthesizing the backbone of the outer chain of N-linked glycans | Saccharomyces cerevisiae | GDP + alpha-mannosyl-1,6-oligosaccharide | - |
