ENZYME entry: EC 2.5.1.149

Accepted Name
Lycopene elongase/hydratase (flavuxanthin-forming).
Reaction catalysed
  • Dimethylallyl diphosphate + all-trans-lycopene + acceptor + H(2)O <=> nonaflavuxanthin + reduced electron acceptor + diphosphate
  • Dimethylallyl diphosphate + nonaflavuxanthin + acceptor + H(2)O <=> flavuxanthin + reduced electron acceptor + diphosphate
Comment(s)
  • The enzyme, characterized from the bacterium Corynebacterium glutamicum, is bifunctional.
  • It catalyzes the elongation of the C(40) carotenoid all-trans- lycopene by attaching an isoprene unit at C-2, as well as the hydroxylation of the new isoprene unit.
  • The enzyme acts at both ends of the substrate, forming the C(50) carotenoid flavuxanthin via the C(45) intermediate nonaflavuxanthin.
  • Cf. EC 2.5.1.150.
