Abstract excerpt

In some purple phototrophic bacteria, the enzyme spheroidene monooxygenase (CrtA) catalyses the final step of carotenoid biosynthesis, introducing a keto group at the C2 position of spheroidene to produce spheroidenone. CrtA from the model purple bacterium Cereibacter (previously Rhodobacter) sphaeroides has a C-terminal extension consisting of a disordered, proline-rich sequence followed by a short region...
