NCBI Protein Information
phytochromobilin:ferredoxin oxidoreductase, chloroplast / phytochromobilin synthase (HY2)
NCBI Summary
Required for biosynthesis of the tetrapyrrole phytochrome chromophore phytochromobilin. Encodes phytochromobilin synthase, a ferredoxin-dependent biliverdin reductase. It is necessary for coupling the expression of some nuclear genes to the functional state of the chloroplast.
