Deletion analysis of the promoter for the Staphylococcus aureus enterotoxin
D determinant indicated that a 52-bp sequence, from -34 to +18, was suffic
ient for sed promoter function and agr regulation. A consensus -10 Pribnow
box sequence, a less conserved -35 sequence, and a TG dinucleotide motif we
re present. Transcribed sequences (+1 to +18) are essential for promoter ac
tivity.
