Structure and biological activities of beta toxin from Staphylococcus aureus.

abstract：:A 3,373-base-pair DNA segment from a clone fortuitously isolated from Saccharopolyspora erythraea by hybridization to an oligodeoxynucleotide probe was sequenced. Computer-assisted analysis of the nucleotide sequence reveals three closely linked Streptomyces open reading frames plus a fourth converging on the others. ...
