The naturally transformable bacterium Haemophilus influenzae Rd contains 1471 copies of the DNA uptake signal sequence (USS) 5'-AAGTGCGGT in its genome. Neisseria meningitidis contains 1891 copies of the USS sequence 5'-GCCGTCTGAA. The USSs are often found in the base paired stem of transcription terminators.
