Abstract excerpt
A contiguous 3-kilobase pair region of DNA was isolated from Group A Streptococcus pyogenes (GAS) that can direct hyaluronic acid (HA) capsule biosynthesis in acapsular mutants as well as heterologous bacteria. The DNA was identified by transposon 916 insertional mutagenesis and subcloned into a plasmid shuttle vector. Mutant acapsular GAS or Enterococcus faecalis containing this plasmid, but not vector alone,...
