Protein

Heme oxygenase 1

Gene

pbsA1

Organism
Nostoc sp. (strain PCC 7120 / UTEX 2576)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the opening of the heme ring with the release of iron. Key enzyme in the synthesis of the chromophoric part of the photosynthetic antennae (By similarity). Upon overexpression in E.coli with PCB:ferredoxin oxidoreductase, CpeS and either CpcB or PecB permits synthesis of phycocyanin-coupled CpcB or PecB.By similarity1 Publication

Catalytic activityi

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