Allelic polymorphism of emm loci provides evidence for horizontal gene spread in group A streptococci.

Proceedings of the National Academy of Sciences of the United States of America - 12 Apr 1994

Bessen D E, Hollingshead S K

Abstract excerpt

Group A streptococci have a virulence regulon containing a single emm locus or two or three distinct and adjacent loci of structurally related emm family genes. The products of the emm gene cluster consist of fibrillar surface proteins, at least some of which are known to contain determinants of type specificity located in their NH2-terminal regions, lying distal to the cell surface. The emm genes can be...
