  • Later on, preQ1 riboswitch was identified as a conserved sequence on the 5' UTR of genes in many gram-positive bacteria and was proved to be associated with synthesis of preQ1. (wikipedia.org)
  • For preQ1 riboswitch from bacteria Bacillus subtilis (Bsu), the anti-terminator is predicted to be less stable than the terminator, as the addition of preQ1 shifts the equilibrium significantly towards the formation of terminator. (wikipedia.org)
