Summary of the EH truncation mutants and their interaction. A, schematic of full-length E and H subunits and truncation mutants used in this study. Secondary structure prediction was obtained from the PSIPRED prediction server. The arrows, cylinders, and lines denote predicted β-sheet, α-helix, and random coil content, respectively. B, table of interaction assay results. Positive and negative interactions are designated with (+ and -), indicating the ability/inability to co-purify by either ion exchange or gel filtration. Interactions not assessed in this study are marked (···).
