TABLE 2.
Main amino acids in contact with the water channel
Listed are amino acids close to the water channel as mapped in Fig 2A. The c-protomer with the deprotonated Glu61 is denoted n. During ATP synthesis, the protomers to the left (in the orientation of Fig. 1A) are the next to be rotated into proton release position and are thus numbered n−1 and n−2. Accordingly, the protomer to the right is denoted n+1.
| Protomer | Amino acid |
|---|---|
| n−2 | Glu46 |
| n−1 | Glu46, Gly47, Arg50, Gly51, Leu54 |
| n | Glu46, Gly47, Lys48, Arg50, Gly51, Leu55, Ala58, Phe59, Met60, Glu61, Ile65 |
| n+1 | Tyr66 |
