Physical properties of residues from TM and EM regions. (A) Relative to EM regions, TM regions contain a larger proportion of highly buried residues (RSA ≤ 0.2). (B) Residues from TM regions tend to be strongly hydrophobic independent of their degree of burial, whereas only the most buried EM residues reach this level of hydrophobicity. Error bars reflect the standard error.
