hemerythrins

he·me·ryth·rins

(hē-mĕ-rith'rinz, hem-ĕ-),
Iron-containing, oxygen-binding proteins in certain invertebrates, with molecular weights approximately that of hemoglobin but differing from hemoglobin in that the molecules do not contain porphyrin groups. Oxygenated hemerythrins is oxyhemerythrin.
[G. haima, blood, + G. erythros, red, + -in]

Four families of oxygen-binding and/or transporting proteins have been characterized into two major groups: iron based, including hemoglobins (Hbs) and hemerythrins (Hrs), and copper based, including two non-homologous families of hemocyanins (Hcs) (Terwilliger et al., 1976; Burmester, 2002; Coates and Decker, 2017).
