Calculated average helical content (and standard deviation) from DSSP analysis of TMD1 (TM1-6) and TMD2 (TM7-12) for each replica of simulated systems 3G5U, 4KSB and 4M1M.

The amount of helical content was also averaged over all three simulations. TMD1 spans residues Trp44-Asp366, while TMD2 spans residues Trp704-Thr1011.螺旋含量（helical content）亦对全部三次模拟的结果取平均值。TMD1（跨膜结构域1，Transmembrane Domain 1）的残基范围为第44位色氨酸至第366位天冬氨酸，而TMD2（跨膜结构域2，Transmembrane Domain 2）的残基范围为第704位色氨酸至第1011位苏氨酸。
