Abstract excerpt

Proteorhodopsin (PR) is a light-driven proton pump found in marine bacteria. More than 1000 PRs are classified as blue-absorbing (λmax ∼ 490 nm) and green-absorbing (λmax ∼ 525 nm) PRs. The color determinant is known to be at position 105, where blue-absorbing and green-absorbing PRs possess Gln and Leu, respectively. This suggests hydrophobicity at position 105 plays a key role in color tuning. Here we...
