Pseudomonas sRNA P9 is a ncRNA that was predicted using bioinformatic tools in the genome of the opportunistic pathogen Pseudomonas aeruginosa and its expression verified by northern blot analysis.[1]
P9 appears to be conserved in several Pseudomonas species in addition to Bordetella species. In both Pseudomonas and Bordetella species P9 appears to be located upstream of a predicted threonine dehydratase gene. P9 has a predicted Rho independent terminator at the 3′ end but the function of P9 is unknown.
