The amino acid sequence of delta haemolysin purified from a canine isolate of <i>S. aureus</i>

Abstract

The amino acid sequence of a staphylococcal delta haemolysin purified from a canine isolate has been determined by a combination of chemical and mass spectroscopic sequence methods. The toxin molecule consists of 26 amino acids residues and is compared with the sequence of a delta haemolysin purified from a human isolate. The two sequences are found to be homologous although amino acid differences are observed in 9 of the 26 residues.
