Hemocyanin is homologous to the phenol oxidases (e.g. tyrosinase) since both proteins have histidine residues, called "type 3" copper-binding coordination centers, as do the enzymes tyrosinase and catechol oxidase. In both cases inactive precursors to the enzymes (also called zymogens or proenzymes) must … Meer weergeven Hemocyanins (also spelled haemocyanins and abbreviated Hc) are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that … Meer weergeven Hemocyanin was first discovered in Octopus vulgaris by Leon Fredericq in 1878. The presence of copper in molluscs was detected even earlier by Bartolomeo Bizio in 1833. … Meer weergeven Although the respiratory function of hemocyanin is similar to that of hemoglobin, there are a significant number of differences in its molecular structure and mechanism.
