Metabolite Identification

Common Name

Iron

Description

Iron is a metallic element found in certain minerals, in nearly all soils, and in mineral waters. Iron is required for life. It exists in all living species, ranging from bacteria to humans. It can be found primarily in blood and it is an essential constituent of hemoglobin, cytochrome, and other components of respiratory enzyme systems. Its chief functions are in the transport of oxygen to tissue (hemoglobin) and in cellular oxidation mechanisms. Depletion of iron stores may result in iron-deficiency anemia. Iron is used to build up the blood in anemia. In humans, iron is involved in several metabolic pathways, some of which include the rofecoxib pathway, magnesium salicylate action pathway, etodolac pathway, and diclofenac pathway. Iron is also involved in several metabolic disorders, some of which include adenine phosphoribosyltransferase deficiency (APRT), porphyria variegata (PV), adenylosuccinate lyase deficiency, and AICA-ribosiduria. The major activity of supplemental iron is in the prevention and treatment of iron-deficiency anemia. Iron has putative immune-enhancing, anticarcinogenic, and cognition-enhancing activities. Iron can be found in a number of food items such as chinese water chestnut, hyssop, daikon radish, and peppermint, which makes it a potential biomarker for the consumption of these food products.

Enzyme Details

1. Heme oxygenase 2

General function:: Involved in heme oxygenase (decyclizing) activity
Specific function:: Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase. Under physiological conditions, the activity of heme oxygenase is highest in the spleen, where senescent erythrocytes are sequestrated and destroyed. Heme oxygenase 2 could be implicated in the production of carbon monoxide in brain where it could act as a neurotransmitter.
Gene Name:: HMOX2
Uniprot ID:: P30519
Molecular weight:: 36032.615

Reactions

Hemoglobin + FADH + Oxygen → Globin + Biliverdin + Carbon monoxide + Iron + FAD + Water	details

3. Ferritin, mitochondrial

General function:: Involved in oxidoreductase activity
Specific function:: Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation.
Gene Name:: FTMT
Uniprot ID:: Q8N4E7
Molecular weight:: 27537.885

Reactions

Fe2+ + Hydrogen Ion + Oxygen → Iron + Water	details

Enzyme Details

4. Ceruloplasmin

General function:: Involved in oxidoreductase activity
Specific function:: Ceruloplasmin is a blue, copper-binding (6-7 atoms per molecule) glycoprotein. It has ferroxidase activity oxidizing Fe(2+) to Fe(3+) without releasing radical oxygen species. It is involved in iron transport across the cell membrane. Provides Cu(2+) ions for the ascorbate-mediated deaminase degradation of the heparan sulfate chains of GPC1. May also play a role in fetal lung development or pulmonary antioxidant defense (By similarity).

Reactions

Enzyme Details

5. Frataxin, mitochondrial

General function:: Involved in cellular iron ion homeostasis
Specific function:: Promotes the biosynthesis of heme and assembly and repair of iron-sulfur clusters by delivering Fe(2+) to proteins involved in these pathways. May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe(2+) to Fe(3+); the oligomeric form but not the monomeric form has in vitro ferroxidase activity. May be able to store large amounts of iron in the form of a ferrihydrite mineral by oligomerization; however, the physiological relevance is unsure as reports are conflicting and the function has only been shown using heterologous overexpression systems. Modulates the RNA-binding activity of ACO1.

General function:: Involved in oxidoreductase activity
Specific function:: Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Also plays a role in delivery of iron to cells. Mediates iron uptake in capsule cells of the developing kidney (By similarity).
