Relative changes in exposure of cell envelope protein Trp residues in different brines
| Brine | Emission Peak (nm) | Trp Exposure to Brine |
|---|---|---|
| M2 | 325 | -- |
| BSS (CTRL), E1 | 329 | ∅ |
| M1, BSS-LS, E2 | 331 | ∅ |
| M4 | 339 | +++ |
BSS is used as the reference point. A shift toward smaller wavelengths indicates more buried residues and a shift toward higher wavelengths more exposed residues. (−) Trp are more buried inside proteins; (∅) Trp are unaffected; (+) Trp are more exposed to the brine environment.
