Figure 4From: Sequence analysis reveals a conserved extension in the capping enzyme of the alphavirus supergroup, and a homologous domain in nodaviruses Overview of the membrane-binding regions in the MTase-GTase of the alto group. Known or predicted membrane association sites are indicated above the C-terminus of the Iceberg region of the alto group, with the same conventions as in Figure 3A. Amphipathic helices are depicted in helical wheel representation.Back to article page
