Globin
The globins are a family of globular proteins which are thought to share a common ancestor. These proteins all incorporate the globin fold a series of eight alpha helical segments. […]
Hemerythrin
Hemerythrin (also spelled haemerythrin; from Greek words αίμα = blood and ερυθρός = red) is an oligomeric protein responsible for oxygen (O2) transport in the marine invertebrate phyla of sipunculids […]
Hemocyanin
Hemocyanins (also spelled haemocyanins) are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O2). […]
Dihydrofolate reductase
Dihydrofolate reductase or DHFR is an enzyme that reduces dihydrofolic acid to tetrahydrofolic acid using NADPH as electron donor which can be converted to the kinds of tetrahydrofolate cofactors used […]
Ornithine decarboxylase
The enzyme ornithine decarboxylase (ODC) catalyzes the decarboxylation of ornithine (a product of the urea cycle) to form putrescine. This reaction is the committed step in polyamine synthesis. In humans […]
Iodothyronine deiodinase
Iodothyronine deiodinases (EC 1.97.1.10 and EC 1.97.1.11) are a subfamily of deiodinase enzymes important in the activation and deactivation of thyroid hormones. thyroxine (T4) the precursor of 353’-triiodothyronine (T3) is […]
Xanthine oxidase
Xanthine oxidase (XO sometimes ‘XAO’) is a form of xanthine oxidoreductase a type of enzyme that generates reactive oxygen species. These enzymes catalyze the oxidation of hypoxanthine to xanthine and […]
Coenzyme Q – cytochrome c reductase
The coenzyme Q : cytochrome c — oxidoreductase sometimes called the cytochrome bc1 complex and at other times complex III is the third complex in the electron transport chain (EC […]
NADH dehydrogenase (ubiquinone)
Complex I (EC 1.6.5.3) (also referred to as NADH:ubiquinone oxidoreductase or especially in the context of the human protein NADH dehydrogenase (ubiquinone)) is an enzyme of the respiratory chains of […]
