Functional analysis of beta- and epsilon-ring carotenoid hydroxylases in Arabidopsis.

The Plant cell - 1 Jun 2003

Tian Li, Magallanes-Lundback Maria, Musetti Valeria, DellaPenna Dean

Abstract excerpt

Lutein and zeaxanthin are dihydroxy xanthophylls that are produced from their corresponding carotene precursors by the action of beta- and epsilon -ring carotenoid hydroxylases. Two genes that encode beta-ring hydroxylases (beta-hydroxylases 1 and 2) have been identified in the Arabidopsis genome and are highly active toward beta-rings but only weakly active toward epsilon -rings. A third distinct activity...
