Northern blot analysis of lacZ in S. aureus 8325-4 containing different ssp promoter elements (nt −312 to +14) fused to lacZ as a single copy in the chromosomal lipase gene, geh. Samples were taken after 4 h of growth, and equal amounts of RNA were analyzed for each sample. Strain KT111 has the ssp promoter element from strain 8325-4 (−35 box, TTGACT), KS30.1 has the ssp promoter element from strain KS30 (−35 box, TTGGCT), and KS30.2 has the ssp promoter element from strain KS30 with a G-to-A substitution at position 4 in the −35 box (TTGACT).
