The group A streptococcal virR49 gene controls expression of four structural vir regulon genes
1 Jan 1995
Abstract excerpt
Within a genomic locus termed the vir regulon, virR genes of opacity factor-nonproducing (OF-) group A streptococci (GAS) are known to control the expression of the genes encoding M protein (emm) and C5a peptidase (scpA) and of virR itself. Within the corresponding genomic locus, opacity factor-producing (OF+) GAS harbor additional emm-related genes encoding immunoglobulin G- and immunoglobulin A-binding proteins...
