Figure 1. Central channel with all FG-repeats after equilibration.

The wall is shown as semi-transparent. Different monomers in FG-domains are colored according to their properties (see SI for details) as following: brown is hydrophobic (HB), yellow is hydrophobic-negative (HN), cyan is hydrophobic-positive (HP), red is purely negative (PN), blue is purely positive (PP), and white is hydrophilic with zero net charge (HL). (A) Side view. A part of the wall is cut for a better representation of inside the channel. (B) Top view.
