on the basis of extensive biochemical studies on psn2 , including the determination of its coding properties and its primary nucleotide sequence , we conclude that this plasmid is not in act involved in enterotoxin b production in s. aureus : although the toxin genes are apparently chromosomal , it is probable that they are part of a special genetic system such as a hitchhiking transposon .
