The outer membrane proteins O-8 and O-9 were specifically bound to the peptidoglycan sacculus in sodium dodecyl sulfate (SDS) solution. Other cellular proteins failed to interact with the peptidoglycan sacculus under the same conditions. When the outer membrane was preheated in SDS solution, the binding did not take place. Optimum binding was observed at pH 8 in the presence of 5 mM Mg2+. A high concentration of sodium chloride strongly inhibited the binding. The effects of these factors on the bindings of O-8 and O-9 required neither the bound nor the free form of Braun's lipoprotein, nor was the binding of either protein necessary for the binding of the other. Proteins O-8 and O-9 were also found in the peptidoglycan sacculus when it was prepared from cells in SDS solution at 60 degrees. A dilution experiment showed that the complex was not an artifact. The mode of interaction between these proteins and peptidoglycan in the preparation was similar to that in the reassembled O-8-O-9-peptidoglycan complex, as judged from the sensitivity to sodium chloride and temperature. The physiological importance of the complex is discussed in relation to the assembly of the outer membrane on the cell surface.
