Multiple heme oxygenase family members contribute to the biosynthesis of the phytochrome chromophore in Arabidopsis.

Plant physiology - 1 Mar 2006

Emborg Thomas J, Walker Joseph M, Noh Bosl, Vierstra Richard D

Abstract excerpt

The oxidative cleavage of heme by heme oxygenases (HOs) to form biliverdin IXalpha (BV) is the committed step in the biosynthesis of the phytochrome (phy) chromophore and thus essential for proper photomorphogenesis in plants. Arabidopsis (Arabidopsis thaliana) contains four possible HO genes (HY...
