Definition & Betydelse | Engelska ordet HEMERYTHRIN

Hemerythrin and myohemerythrin are essentially colorless when deoxygenated, but turn a violet-pink in the oxygenated state.
Models for hemerythrin, an enzyme with a diiron active site, and xanthine oxidase, a molybdoenzyme, have been examined.
The active site of MetAP2 has a structural motif characteristic of many metalloenzymes—including the dioxygen carrier protein, hemerythrin; the dinuclear non-heme iron protein, ribonucleotide reductase; leucine aminopeptidase; urease; arginase; several phosphatases and phosphoesterases—that includes two bridging carboxylate ligands and a bridging water or hydroxide ligand.
The study of these compounds is inspired by oxygen-carrying proteins such as myoglobin, hemoglobin, hemerythrin, and hemocyanin.
Dawson JW, Gray HB, Hoenig HE, Rossman GR, Schredder JM, Wang RH (1972) A magnetic susceptibility study of hemerythrin using an ultrasensitive magnetometer.
They have synthesized analogues of the diiron carboxylate cores of MMO and related carboxylate-bridged diiron proteins such as the dioxygen transporter hemerythrin.
Major diiron enzymes include hemerythrin, some ribonucleotide reductases, some methane monooxygenases, purple acid phosphatases, and ferritin.
Krukenberg examined biological pigments such as hemerythrin, lipochromes, and the colours of eggs (being the first to identify biliverdin as a pigment) and feathers.
