    2.7.1.148 | 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. |

| 2.7.1.148 | free enzyme, in complex with substrates 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol, ADP and with adenyl imidodiphosphate, to 1.0, 1.54, 1.0, and 1.0 A resolution, respectively. The structures present a characteristic galactose/homoserine/mevalonate/phosphomevalonate kinase superfamily alpha/beta-fold with a catalytic center located in a cleft between two domains and display clear substrate and ATP binding pockets |

| 2.7.1.148 | 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 |
