dc.description.abstract | Mannosylphosphorylated N-glycans found in yeasts can be converted to those containing mannose-6-phosphate, which is a key factor for lysosomal targeting. In the traditional yeast Saccharomyces cerevisiae, both ScMNN4 and ScMNN6 genes are required for efficient mannosylphosphorylation. ScMnn4 protein has been known to be a positive regulator of ScMnn6p, a real enzyme for mannosylphosphorylation. On the other hand, YIMpo1p, a ScMnn4p homologue, mediates mannosylphosphorylation in Yarrowia lypolytica without the involvement of ScMnn6p homologues. In this study, we show that heterologous expression of YlMpo1p can perform and enhance mannosylphosphorylation in S. cerevisiae in the absence of ScMnn4p and ScMnn6p. Moreover, the level of mannosylphosphorylation of N-glycans enhanced by YIMpo1p overexpression is much higher than that with ScMnn4p overexpression, and this is highlighted further in Scmnn4- and Scmnn6-disrupted mutants. When YlMpo1p overexpression is applied to glyco-engineered S. cerevisiae in which the synthesis of immunogenic glycans is abolished, a great increase of bi-mannosylphosphorylated glycan is observed. Through an in vitro process involving the uncapping of the outer mannose residue, this bi-mannosylphosphorylated structure is changed to a biphosphorylated structure with high affinity for mannose-6-phosphate receptor. The superior ability of YlMpo1p to increase bi-mannosylphosphorylated glycan in yeast shows promise for the production of therapeutic enzymes with improved lysosomal targeting capability.
