The novel biotechnology of cell surface anchor engineering is applied to the building industry. Heterologous gene expression is attracted to the cell surface. Localized on the cell surface, proteins are involved in morphogenesis, identification and transport of external substances, signal transduction, and a host of other activities. By fusing with the domains for cell wall or plasma membrane anchoring, functional heterologous proteins or medicines are genetically immobilized on the cell surface in cell anchor surface engineering. Furthermore, immobilization on the cell surface itself preserves enzymatic characteristics and strengthens the structural stability of the medicines or proteins that are on display. The medicines and proteins on display have the ability to interact with high-molecular-mass environmental materials that are not able to enter cells.
