Outer membrane enriched material from six strains of Fusobacterium nucleatum was analysed by SDS-PAGE. The protein profiles of all the strains were dominated by proteins with molecular masses of about 40 kDa, and a very high degree of homology in relation to apparent molecular masses was observed. In all strains except Fev1, one of the most dominant proteins exhibited heat modifiable properties, having an apparent molecular mass of about 38 kDa and 42 kDa when heated in SDS at 50 and 100 degrees C, respectively. None of the proteins of the outer membrane of F. nucleatum Fev1 demonstrated such heat modifiable properties. The 40 kDa protein, and several other proteins, appear to be both exposed on the cell surface and peptidoglycan associated.
