Glycoprotein-carbohydrate matrix

There is little work that definitively describes the composition of fungal adhesives. However, it is apparent that fungi do not share either common adhesives or mechanisms for adhesion. One factor that does appear with regularity is that the surface of fungal germ tubes are typically ensheathed by a glycoprotein/carbohydrate matrix (41, 51.r JU.) / and...

Thus, in plaque, both carbohydrate and protein material contribute to the matrix. While the origins of these components have been indicated, other hypotheses were advanced to explain incorporation of salivary proteins in plaque (IS). For example, Leach has proposed that plaque proteins arise as a result of the action of glycosidases e.g., neuraminidase) on salivary glycoproteins (5). Data of Briscoe et al. suggest, however, that neuraminidase does not modify adsorption behavior of salivary proteins (22).
