NPC and NPCa protein evloutionary rates. (a) Comparison of the evolutionary rates for several NPC and NPCa proteins. The evolutionary rate for a marker corresponds to the average distance estimated between species. (b) The evolutionary rates mapped onto the NPC structure with a color code: green, slowly evolving marker (average distance < 1); yellow, marker evolving at an average rate (1 < average distance < 2); red, rapidly evolving marker (2 < average distance < 3); dark red, very rapidly evolving marker (average distance > 3).
