Добрый путь!
А solcrane - тоже будет.

Hemocyanins are the oxygen transport proteins of many arthropods and molluscs. They are extremely large (up to 9 MDa) and have many oxygen-binding units per particle. Contrary to iron-based blood of vertebrates and some invertebrate phyla, the active site is a Cu atom pair that reversibly binds oxygen. There are two distinct hemocyanin proteins; one found in arthropods, the other in molluscs. Their subunit sizes, architectures, aggregation states, and tertiary structures are all different. There is little sequence similarity between the two hemocyanins. Nonetheless, their spectroscopic properties are largely indistinguishable.
