Abstract
The structural gene encoding streptococcal pyrogenic exotoxin type B, designated speB, was cloned in Escherichia coli and localized onto a 4.5-kilobase BamHI-BglII DNA fragment. Streptococcal pyrogenic exotoxin type B, partially purified from E. coli clones, was immunologically related to streptococcus-derived toxin. Also, toxin derived from either E. coli or Streptococcus pyogenes had similar lymphocyte mitogenic activity and molecular weight (29,300) and displayed comparable microheterogeneity when evaluated by isoelectric focusing.Entities:
