Associations of crtL with chemical compounds

  • We have cloned a cyanobacterial gene encoding lycopene cyclase, an enzyme that converts the acyclic carotenoid lycopene to the bicyclic molecule beta-carotene [2].
  • When the subsequent genes from E. uredovora which encode for lycopene cyclase and beta-carotene hydroxylase were present, neurosporene, the phytoene desaturase product of R. capsulatus, was subsequently converted to the monocyclic beta-zeacarotene and its monohydroxylation product [3].
