Table 1 Correspondence between channels identified in computational studies and this work.

Channel names are listed followed by the species they were assigned to conduct in the original study. Channels in the same column are nearly identical unless otherwise noted.

*The authors calculated a high (~22 kcal/mol) activation energy barrier for water travel through this channel, rendering it “virtually impermeable” to water (see main text for discussion).

†Encompasses approximately two-thirds of channel 1 length.

‡Encompasses approximately three-fourths of channel 2 length.

§Encompasses approximately one-half of channel 5 length.

¶Encompasses approximately three-fourths of channel 4ci length.

||Encompasses approximately two-thirds of channel 5 length.
