Fig. 8From: Retro-protein XXA is a remarkable solubilizing fusion tag for inclusion bodiesCharge distribution and oligomer model of XXA. a The charge distribution of the XXA monomer was analyzed using the tertiary structure from tFold. b A schematic diagram was constructed to show the trimer and tetramer models of XXA. Red color represents that the same kind of charge was distributed on the outer surface of the XXA oligomerBack to article page
