1PA14_52570 (RsmA)Post-transcriptional-TssA1 (PA14_00990) transcriptRsmA binds the tssA1 mRNA in a region overlapping the ribosome binding site (RBS), which is thought to form a stem-loop structure.
2PA14_52570 (RsmA)-TssA2 (PA14_43050) transcriptRsmA binds the tssA2 mRNA in a region overlapping the ribosome binding site (RBS), and contains the core GGA motif.
3PA14_52570 (RsmA)-TssB3 (PA14_34070) transcriptRsmA binds the tssB3 mRNA in a region overlapping the ribosome binding site (RBS), and contains the core GGA motif.
4PA14_20290 (AmrZ)Transcriptional+TssA1 (PA14_00990) promotorAmrZ binds to all three assessed T6SS promoter regions and activates expression of H1-T6SS (tssA1).
5PA14_20290 (AmrZ)Transcriptional-TssA2 (PA14_43050) promotorAmrZ binds to all three assessed T6SS promoter regions and represses H2-T6SS (tssB2) transcription and H2-T6SS bacterial Killing.
6PA14_20290 (AmrZ)Transcriptional+TssB3 (PA14_34070) promotorAmrZ binds to all three assessed T6SS promoter regions and activates expression of H3-T6SS (vgrG3).
7PA14_48150 (QslA)QS regulator-H2-T6SS (PA14_43050) promotorThe expression of H2-T6SS machinery genes was controlled at a transcriptional level by QslA.
