چکیده
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.

Acceleration of dextransucrase activity of Streptococcus mutans by secretory immunoglobulin A.
The effect of immunoglobulins on the activity of dextransucrase purified from Streptococcus mutans strain HS-6 is described. When human salivary immunoglobulin A (IgA) or colostral IgA, either natured or denatured, was incubated with dextransucrase, the rate of the dextran synthesis was markedly accelerated, whereas human serum IgA or IgG neither accelerated nor inhibited the enzyme activity. T...

Background: Little is known about pulmonary complications induced by Sulfur Mustard (SM), as a chemical warfare agent,especially considering its long term effects. The present study was carried out to investigate the association of α1-antitrypsin(A1AT), Complement component C5a, and Secretory Immunoglobulin A (sIgA) with long-term pulmonary complications on SMexposedindividuals, 20 years after ...
متن کاملInhibition of Streptococcus mutans Adherence to Saliva- Coated Hydroxyapatite by Human Secretory Immunoglobulin A (S-IgA) Antibodies to Cell Surface Protein Antigen I/II: Reversal by IgAl Protease Cleavage
The effect of human secretory immunoglobulin A (S-IgA) and serum antibodies to surface protein antigen (Ag) 1I/ on the adherence of Ag VII-bearing Streptococcus mutans and of free Ag VII to saliva-coated hydroxyapatite (SHA) was investigated. The inhibition by S-IgA of binding of both S. mutans and free Ag IJI to SHA was dependent on antibody to Ag VII. Essentially no difference was found betwe...
متن کاملPreferential utilization of the glucosyl moiety of sucrose by a cariogenic strain of Streptococcus mutans.
The utilization of sucrose by a cariogenic strain of Streptococcus mutans was studied. The soluble and cell-bound sucrose-dependent, polymer-forming sucrase activities constitutively produced by the bacteria during growth on glucose were measured. About eight times more dextransucrase activity was present than levan-sucrase activity. During various states of growth on sucrose, S. mutans accumul...
متن کاملAntibody-mediated inhibition of dextran-sucrose-induced agglutination of Streptococcus mutans.
Immune sera to strains of Streptococcus mutans were found to inhibit agglutination of bacterial suspensions to which either high-molecular-weight dextran or sucrose was added. This inhibitory activity was shown to be mediated by antibody of the immunoglobulin G class. A semiquantitative assay was developed which demonstrated cross-inhibition of dextran/sucrose-induced agglutination among severa...
