RESUMO
An 87-kDa glucan-binding protein (GBP) of Streptococcus sobrinus B13 (serotype d) was isolated and purified from extracellular culture supernatant by using affinity chromatography on Sephadex G-50 and elution with a guanidine HCl gradient. Western blot (immunoblot) analysis showed it to be antigenically related, but not completely identical, to the 74-kDa GBP of Streptococcus mutans Ingbritt. The 87-kDa GBP has no glucosyltransferase activity. A possible role for this GBP in the cariogenicity of S. sobrinus B13 is suggested.
