Occurrence and Characterization of S-Layers in Oral Bacteria
The first observations of additional surface layers composed of regularly arranged protein subunits in oral bacteria were reported at the beginning of this decade (Kornman and Holt 1981, Lai et al. 1981, Ranta et al. 1983, Haapasalo et al. 1985). The function of S-layers is not known, but they may play a crucial role in complex interactions of cells with their environment. Interestingly, bacteria causing human infections have rarely been shown to possess an S-layer.
