The Roles of UmuD in Regulating Mutagenesis

Figure 3

Protein interaction sites on UmuD. (a) The 𝛽 clamp interacts with residues 14–19, 24, 52, and 126 (blue) [53]. RecA interacts with residues 34, 81, 57, 67, and 112 (cyan) [49]. DinB interacts with residue 91 on UmuD (green) [30]. (b) ClpXP interacts with residues 9–12, 33–37, 41–51, and 85–109 (red) [123]. Lon binds to regions close to the residues that are important for interaction with ClpXP, residues 15–19 (violet) [125].
