-, O67060
Gel-filtration and analytical ultracentrifugation indicate that AaIspE is a monomer in solution
additional information
-
the enzyme subunit displays the alpha/beta fold characteristic of the galactose kinase/homoserine kinase/mevalonate kinase phosphomevalonate kinase superfamily, arranged into cofactor and substrate-binding domains with the catalytic center positioned in a deep cleft between domains, quarternary structure, overview
Crystallization/COMMENTARY
ORGANISM
UNIPROT ACCESSION NO.
LITERATURE
AaIspE is crystallized by vapor diffusion. Ordered and reproducible crystals of AaIspE are obtained and multiple-wavelength anomalous dispersion methods are applied to obtain the initial phases. 3 medium-resolution complex crystal structures are determined. The crystals are isomorphous with two molecules in the asymmetric unit.

in complex with ADP, to 2.0 A resolution, and comparison with a monoclinic crystal form of a ternary complex of Escherichia coli 4-diphosphocytidyl-2C-methyl-D-erythritol kinase also with two molecules in the asymmetric unit. The molecular packing is different in the two forms. In the asymmetric unit of the triclinic crystal form the substrate-binding sites are occluded by structural elements of the partner, suggesting that the triclinic dimer is an artefact of the crystal lattice. The surface area of interaction in the triclinic form is almost double that observed in the monoclinic form

Purification/COMMENTARY
ORGANISM

LITERATURE
The gene is preceded by a His6 tag to enable purification of the recombinant protein via metal-chelating affinity chromatography. The polyhistidine tag is removed by thrombin-mediated proteolysis, followed by purification with anion-exchange chromatography. Purity of the sample is assessed by SDS-PAGE and MALDI-TOF MS.
