Construction of translational fusion vector with 90-bp deletion of the 5’-UTR of phenazine biosynthetic operon: To determine the function of the 5’-UTR on translation of the phenazine biosynthesis genes, translation fusion vectors were created containing the sequence from the phenazine biosynthetic operon promoter to the 20th codon of PhzX with or without 90-bp sequence of 5’-UTR of phenazine biosynthetic operon (Fig 4B).
