Protein

Heme oxygenase 1, chloroplastic

Gene

HO1

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Catalyzes the opening of the heme ring to form the open-chain tetrapyrrole biliverdin IX with the release of iron and carbon monoxide (CO). Is a key enzyme in the synthesis of the chromophore of the phytochrome family of plant photoreceptors. Essential for photoperiod response and repression of flowering through cytochromes that inhibit flowering by affecting both HD1 and EHD1 flowering pathways.2 Publications

Catalytic activityi

Protoheme + 3 AH2 + 3 O2 = biliverdin + Fe2+ + CO + 3 A + 3 H2O.
