...Roy E. Weber; Jane W. Behrens; Hans Malte; Angela Fago SUMMARY With the aim of understanding the molecular underpinnings of the enormous variation in the temperature sensitivity of hemocyanin–O 2 affinity encountered in crustaceans, we measured O 2 binding to Carcinus maenas hemocyanin at two...

...N. B. Terwilliger; M. C. Ryan; D. Towle SUMMARY Hemocyanin, the blue blood protein of many arthropods and molluscs,reversibly binds oxygen at its highly conserved copper–oxygen-binding sites and supplies tissues with oxygen. Cryptocyanin, closely related structurally and phylogenetically...

...Nora B. Terwilliger; Karen Dumler ABSTRACT Hemocyanin is present throughout the decapod crustacean’s life, usually as one-hexamer and two-hexamer oligomers. Hemocyanins of some decapod crustaceans undergo changes in subunit composition and oxygen affinity during development. Maternal hemocyanin...

...Nora B. Terwilliger ABSTRACT Oxygen-transport proteins are multisubunit, circulating molecules that provide an efficient supply of oxygen to metabolically active metazoans. Hemoglobins, hemerythrins and hemocyanins have evolved in both structural and functional diversity and exhibit functional...

...A. Christine Brown; Nora B. Terwilliger ABSTRACT The in vivo oxygen-binding characteristics of Cancer magister whole hemolymph were compared across developmental stages with those of purified hemocyanin. When the 25S hemocyanins from first-instar juvenile and adult C. magister were dialyzed against...

...Nora B. Terwilliger; A. Christine Brown ABSTRACT Calcium and magnesium ions raise the oxygen affinities of 25S hemocyanins of both first-instar juvenile and adult Cancer magister . A physiologically relevant change in magnesium concentration from 16 to 32mmol l −1 changes first-instar juvenile...
