Pseudomonas sRNA P11 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] P11 is located between a putative threonine protein kinase and putative nitrate reductase and is conserved in several Pseudomonas species. P11 has a predicted Rho independent terminator at the 3′ end but the function of P11 is unknown.
