Streptococcus mutans was classified by the electrophoretic properties of glucosyltransferases (GTases) and fructosyltransferases (FTases). The cells of serotypes a, d and g did not release extracellular FTases, although those from other serotypes did. The enzymes from cells of serotypes d and g synthesized a good deal of insoluble polysaccharide compared with other serotypes. The enzymes were applied to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), and polyacrylamide gel-isoelectric focussing (PAG-IEF). Gels were stained for their activity and protein content. Enzymes belonging to the same serotype gave the same specific pattern on both gels. The seven serotypes could be classified into the following four groups: serotypes d and g, serotype a, serotypes c, e and f, and serotype b. The results agree well with some previous reports based on other methods. The molecular weights of three GTase bands were 156K, 146K and 135K, and of four kinds of FTase bands were 108K, 95K, 80K and 76K. The isoelectric points of main enzymes were 4.25, 4.60, 5.00, 5.55 and 5.70. Those of FTases were 4.25 and 4.60.
