Fig 2. Analysis of the dimer and tetramer interfaces in MtuDAH7PS.

Fig 2

(A) Surface representation of the dimer interface of MtuDAH7PS (PDB 3NV8). Residues contributing to this interface are displayed as red sticks. Residues identified to contribute to the dimer interface by PISA include residues 2–13, 15, 44, 47–48, 51, 54–58, 60, 62–63, 92, 94–96, 99, 165–167, 170–171, 173–175, 177–178, 180–182, 184–186, 189, 260, 263 and 265 of chain A, and residues 1, 3–13, 47–48, 51, 54–58, 60, 62–63, 91–92, 94–97, 99–100, 165, 167–168, 170–171, 173–175, 177–182, 184–186, 188–190,296, and 260 of chain B. (B) Surface representation of the tetramer interface of MtuDAH7PS (PDB 3NV8). Residues contributing to this interface are displayed as blue sticks. Residue numbers are described in the main text. (C) Hydrophobic grove in the tetramer interface and the interaction with Phe227 from the other chain. (D) Positions of the two Gly232 residues on the tetramer interface, succeeding helices α2a and α2b.
