THE HIGH RESOLUTION STRUCTURE OF ANNEXIN III SHOWS DIFFERENCES WITH ANNEXIN V
Overview
The structure of recombinant human annexin III was solved to 1.8 A, resolution. Though homologous to annexin I and V, the annexin III, structure shows significant differences. The tryptophan in the calcium, loop of the third domain is exposed to the solvent, as in the structure of, annexin V crystallized in high calcium concentrations, although the, annexin III crystals were prepared at low calcium concentrations. The, position of domain III relative to the other domains is different from, both annexin V and I, suggesting further flexibility of the molecule. The, entire N-terminus of the protein is well-defined in the present structure., The side chain of tryptophan 5 interacts with the hinge region of the, hydrophillic channel, which could have an effect on the potential mobility, of this region, as well as on its possible calcium channel behavior.
