Table illustrates that the Tau protein primarily contains BTB and Transcription factor zinc-finger domains at the N-and C-termini, suggesting that it has dimerization and zinc finger structures. Table shows that Tau protein mostly has DksA C4-type domains at the N-terminus and C-terminus. This suggests that it binds to DNA by binding to ppGpp, which is similar to how RNA polymerase does it. Table demonstrates that the Tau protein primarily contains the Bromo and Sporulation initiation factor Spo0A C-terminal at the N-terminus and C-terminus. This suggests that the protein has an α-helix structure and binds to DNA through a helix-turn-helix structure. Table illustrates that Tau protein primarily contains the Transcription regulator Myc N-terminal, STAT transcription factor protein interaction, ETS, Fork-head, RFX-type winged-helix domains at the N-terminus and C-terminus.
