| + | The crystal structure of the Ta1207 protein from Thermoplasma acidophilum is reported. Ta1207 was identified in a screen for high-molecular-weight protein complexes in T. acidophilum. In solution, Ta1207 forms homopentamers of 188 kDa. The crystal structure of recombinant Ta1207 solved by Se-MAD at 2.4 A resolution revealed a complex with fivefold symmetry. In the crystal lattice, calcium ions induce the formation of a nanocage from two pentamers. The Ta1207 protomers comprise two domains with the same novel alpha/beta topology. A deep pocket with a binding site for a negatively charged group suggests that Ta1207 functions as an intracellular receptor for an unknown ligand. Homologues of Ta1207 occur only in Thermoplasmatales and its function might be related to the extreme lifestyle of these archaea. The thermostable Ta1207 complex might provide a useful fivefold-symmetric scaffold for future nanotechnological applications. | ||
