A novel cell-surface display system was constructed in Aspergillus oryzae. Each of the five genes encoding the putative cell-wall-localized protein from the A. oryzae genome was cloned and these cell-surface anchor functions were examined by fusion to the C-terminal of the green fluorescent protein (GFP). Using the MP1 and CWP proteins as anchor proteins, GFP signals were strongly observed on the cell surface of recombinant A. oryzae. When these proteins were used as anchor proteins for cell-surface display of beta-glucosidase from A. oryzae, enzyme activity was detected on the cell surface. In particular, beta-glucosidase activity of recombinant A. oryzae using MP1, a putative glycosylphosphatidylinositol (GPI) anchor protein was higher than CWP. Based on these results, it was concluded that the MP1 protein can act as a GPI-anchor protein in A. oryzae, and the proposed cell-surface display system using MP1 allows for the display of heterogeneous and endogenous proteins.
