Other proteins found to bind influenza, and that are found in Spn’s cell or cell surface accessible include Glyceraldehyde-3-phosphate dehydrogenase, NADP-dependent (GapN), Phosphoenolpyruvate-protein phosphotransferase (Ptsl), Acetyl-coenzyme A carboxylase carboxyl transferase subunit alpha (AccA), Cell division ATP-binding protein (FtsE) and the putative competence-damage inducible protein (CinA), among others (Fig 1E and S1 Data). Here, GAPDH is linked to influenza.
