In general, many surface proteins of Gram-positive bacteria are covalently attached to the cell wall. Staphylococcal protein A (SpA) is a 40–60 kDa surface protein which has often been used as a model surface display system to study anchoring mechanisms. Staphylococcus aureus is a Gram-positive, round-shaped bacterium that secret surface proteins across septal membranes for assembly into the bacterial cross-wall. Surface proteins of Staphylococcus aureus play a very crucial role in the pathogenesis of human infections and are anchored to the cell wall envelope by sortases.

• They must have a strong anchoring domain to ensure that exogenous proteins can be immobilized on the surface.
• They must be compatible with foreign proteins, be able to form fusion proteins, and should not be able to interact with each other.
• They must be resistant to protease hydrolysis.
• Transmembrane proteins
• LPXTG-like proteins
• Cell wall binding proteins
• Single cell membrane architecture and translocation through only one membrane
• The Gram-positive bacteria have been shown to be more rigid
• The cell is viable in harsh conditions and thus suitable for high-speed flowcytometric sortings.
