TatA2-45 variants and their physical properties
| TatA2-45 variants | Number of amino acids in the TMH | Sequence range of the TMH | TMH length (Å) | Number of helix turns | Variation |
|---|---|---|---|---|---|
| TatA2-45 LALALAL | 23 | Pro8–Pro30 | 34.5 | 6.4 | extension of the TMH |
| TatA2-45 LALAL | 21 | Pro8–Pro28 | 31.5 | 5.8 | extension of the TMH |
| TatA2-45 LAL | 19 | Pro8–Pro26 | 28.5 | 5.3 | extension of the TMH |
| TatA2-45 | 16 | Pro8–Pro23 | 24.0 | 4.4 | natural TMH |
| TatA2-45 ΔLIL | 13 | Pro8–Pro20 | 19.5 | 3.6 | shortening of the TMH |
The length of the TMH was calculated based on a 1.5 Å translation per residue, and 3.6 residues per helix turn.
