title: Influence of secretory immunoglobulin A and purified secretory component on dextran-sucrase activity of Streptococcus mutans.
abstract: The net stimulation of dextransucrase EC 2.4.1.5) activity from Streptococcus mutans HS6 by dextran, secretory immunoglobulin A, or secretory component was investigated. Approximately equal stimulation resulted from treatment with these three components.
