Surface hydrophobicity, adherence, and aggregation of cell surface protein antigen mutants of Streptococcus mutans serotype c.
The pac gene of the serotype c strain Streptococcus mutans MT8148 encodes a cell surface protein antigen (PAc) of approximate 190 kilodaltons. The serotype c strain S. mutans GS-5 does not produce the 190-kilodalton PAc but produces a lower-molecular-weight protein that reacts with anti-PAc serum. The SphI-BamHI fragment of the pac gene was ligated with the S. mutans-Escherichia coli shuttle ve...
متن کاملCell surface components of Streptococcus sanguis: relationship to aggregation, adherence, and hydrophobicity.
Cell surfaces of aggregation, adherence, and hydrophilic variants of Streptococcus sanguis were compared with cell surfaces of the parent strain with regard to their protein and antigenic constituents. Cell surface molecules were released by digestion with mutanolysin. Extraction with sodium dodecyl sulfate (SDS) urea, lithium diiodosalicylate, and boiling water did not solubilize any material ...
متن کاملSaliva-binding region of Streptococcus mutans surface protein antigen.
A 190-kDa surface protein antigen (PAc) of Streptococcus mutans binds to human salivary components. For detection of specific binding of the PAc protein to human salivary components, a simple sandwich assay was used. Microtiter plates precoated with recombinant PAc (rPAc), PAc fragments, or S. mutans whole cells were allowed to react with human whole saliva and then were incubated with biotinyl...
متن کاملRelationship Between Cell Surface Hydrophobicity and Degradation of Hexadecane
Some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. Those strains which have a high percentage of these features are more effective at biodegradation. The present experiments were designed to measure these parameters. In this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...
متن کاملSucrose-dependent cell adherence and cariogenicity of serotype c Streptococcus mutans.
Four strains of serotype c Streptococcus mutans differing in glucosyltransferase (GTase) and fructosyltransferase (FTase) activities were examined. These strains had been made resistant to streptomycin. FTase activity of an S. mutans clinical variant, MT6801R, which forms large mucoid colonies on sucrose-containing agar, was considerably higher than that of a typical serotype c strain, MT8148R,...
