Enolase fromStreptococcus sobrinusis an immunosuppressive protein

Cellular Microbiology, 2004
A strategy of Streptococcus sobrinus, a major agent of dental caries, to survive and colonize the host consists of the production of a protein that suppresses the specific antibody responses. We have cloned the gene coding for a protein with immunosuppressive activity. It contains an open reading frame of 1302 base pairs encoding a polypeptide with 434
