Wenxiang diagrams illustrate protein helices as spirals on a plane and thus have the advantage overhelical wheels of being planar graphs. Wenxiang 3.0 extends the original version by adding threemajor features: (1) individual amino acid residues can be colored according to their evolutionaryconservation in comparative multiple sequence alignments using CONSURF encoding; (2) α, π, and3/10 helices can be illustrated by overlaying arcs representative of the pitches of these helices; and,(3) the phy…
