Comparison of the Secondary Structure of the Two Variants of wsMURs

205–260 nm wsMUR-TM wsMUR-TM_v2
Helix 53.7% 55.6%
Antiparallel 4.6% 4.4%
Parallel 4.9% 4.6%
Beta-Turn 13.9% 13.6%
Others 22.9% 21.8%

wsMUR-TM = first variant of the water-soluble human μ opioid receptor transmembrane portion; wsMUR-TM_v2 = modified (second) variant of the water-soluble human μ opioid receptor transmembrane portion. Buffer condition: 0.01% Sodium dodecyl sulfate, 5 mM sodium phosphate, pH = 7.0 in room temperature.
