Oxygenases
Oxidases that specifically introduce DIOXYGEN-derived oxygen atoms into a variety of organic molecules.
Oxygenase
D006242
Haptoglobins
Plasma glycoproteins that form a stable complex with hemoglobin to aid the recycling of heme iron. They are encoded in man by a gene on the short arm of chromosome 16.
Haptoglobin

Heme
The color-furnishing portion of hemoglobin. It is found free in tissues and as the prosthetic group in many hemeproteins.
Ferroprotoporphyrin,Protoheme,Haem,Heme b,Protoheme IX
D006419
Heme Oxygenase (Decyclizing)
A mixed function oxidase enzyme which during hemoglobin catabolism catalyzes the degradation of heme to ferrous iron, carbon monoxide and biliverdin in the presence of molecular oxygen and reduced NADPH. The enzyme is induced by metals, particularly cobalt.
The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.
