Abstract
The structural and functional properties of hemocyanin from the mediterranean lobster Palinurus elephas have been recently published (1). The results obtained have shown that:
-
a)
the protein exists in only two aggregation states (monomeric and hexameric);
-
b)
the monomeric subunits are not homogeneous, but belong to at least 3 or 4 different classes; c) the 02 binding of the hexamer is cooperative, and both pH and (Ca++ dependent; d) the Bohr effect of the hexamer in the presence of Ca++ is negative and similar to that of the previously characterized Panulirus interruptus hemocyanin; e) the monomers are non cooperative and have relatively low 02 affinity (somewhat similar to that of the T state of the hexamer).
