The zeaxanthin operon is naturally found in many plants and bacteria. The operon encodes five genes, which enable the production of the yellow pigment zeaxantin.

The five genes present in the zeaxanthin operon are:

  • CrtE
  • CrtB
  • CrtI
  • CrtY
  • CrtZ

The enzymes encoded by these genes and the products formed are shown in figure .

Lycopene

The genes CrtE, CrtB and CrtI produce lycopene from farnesyl diphosphate (an intermediate in the mevlonate pathway).

Lycopene is a red pigment (found in tomatoes), which also has extremally powerful antioxidant properties and may possibly help protect you from cancer.

B-carotene

B-carotene is produced by cyclising lycopene, which is carried out by encoded in CrtY
