*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.
