Comments concerning this interaction

Using [32]P labeled DNA with Trl binding sites and lacking ttk binding sites, the addition of ttk to Trl and DNA increased DNA-protein complexes observed by EMSA. This was taken as evidence of a Trl-ttk protein-protein interaction.

Interaction in vitro; proteins produced as a recombinant fusion proteins in bacterial system.
