The multimeric structure of HpMinE. A. Ribbon view of the multimeric structure of HpMinE generated by the sixfold symmetry in the crystal. The width and length of a single turn of the multimeric structure are approximately 5.5 and 12.5 nm respectively. The N-terminus of each HpMinE is shown as a red sphere. B. Close-up view of the interacting residues in the interface between two dimers (blue and green). Residues I55, H56 and F57 are involved in hydrophobic interaction, and H56 makes a hydrogen bond with D54.
