Insights into Protein–DNA Interactions through Structure Network Analysis
Figure 6
Clusters (P-p, P-S, and P-B) from the 434 repressor protein of the HTH group.
The P-p (yellow), P-S (green), and P-B (blue) clusters are shown in the bacteriophage 434 repressor protein (1rpe) which belongs to the HTH group. The P-B clusters are present in the recognition helix that interacts with the major groove of the DNA and the P-p and the P-S clusters are present in the other interacting region that interacts with the minor groove.
