1.A.85.1.3
Echovirus E30 polyprotein (128 aas; fragment).  An intracellular (endomembrane) pore-forming peptide toxin which induces membrane permeability due to two consecutive hydrophobic segments that may form an α-helix-turn-α-helix hairpin membrane anchor that provides the basis for oligomeric pore formation (Sánchez-Martínez et al. 2012).  This protein is derived from the Coxsackle virus B2 protein of 2187 aas (Q9YLG5) and may interact with a Ryanodine receptor (Schilling et al. 2013).
