(a) Experimental 4.0 Å SAD electron density map. (b) Experimental 3.09 Å SIRAS electron density map. Both maps are contoured at 1.5σ. The model shown corresponds to PDB code 2cf4
(Schoehn et al., 2006). (c) Anomalous Fourier map contoured at 10σ showing that the Eu3+ ion of the [Eu(DPA)3]3− complex is located between two monomers on the large channel side of the particle. This dimer is considered as the minimal building block to form the whole TET1 particle. |
