Mechanistic studies of the phytochromobilin synthase HY2 from Arabidopsis.

The Journal of biological chemistry - 10 Oct 2008

Tu Shih-Long, Chen Hsiu-Chen, Ku Li-Wen

Abstract excerpt

Phytochromobilin (PPhiB) is an open chain tetrapyrrole molecule that functions as the chromophore of light-sensing phytochromes in plants. Derived from heme, PPhiB is synthesized through an open chain tetrapyrrole intermediate, biliverdin IXalpha (BV), in the biosynthesis pathway. BV is subsequently reduced by the PPhiB synthase HY2 in plants. HY2 is a ferredoxin-dependent bilin reductase that catalyzes the...
