| 4.3.3.7 | at 239K using the hanging drop-vapor diffusion method, at 1.5 A resolution. The four subunits of the asymmetric unit assemble to form a tetramer with an approximate 222 symmetry. At the active site, three residues Tyr132, Thr43 and Tyr106 are observed to constitute a catalytic triad. Has a unique extensive dimerdimer interface that is mediated by strong hydrophobic interactions supplemented by two sets of three hydrogen bonds between four polar residues. Belongs to space group P2(1)2(1)2(1) with cell parameters a = 67.03 A, b = 120.52 A, c = 161.1 A |

| 4.3.3.7 | atomic resolution at 1.45 A, crystal structure confirms the dimeric quarternary structure, reveals that the dimerization interface of the MRSA-DHDPS enzyme is more extensive in buried surface area and noncovalent contacts than the equivalent interface in tetrameric DHDPS enzymes from other bacterial species |

| 4.3.3.7 | by the hanging drop-vapour diffusion method, mutants K161A and K161R solved at resolutions of 2.0 and 2.1 A, respectively. They show no changes in their secondary or tertiary structures when compared to the wild-type structure. Crystal structure of mutant K161A with pyruvate bound at the active site solved at a resolution of 2.3 A, reveals a defined binding pocket for pyruvate that is thus not dependent upon lysine 161 |

| 4.3.3.7 | by the hanging-drop vapour-diffusion method, to 2.1 A resolution. The crystal belongs to space group P42212, with unit-cell parameters a = b = 105.5, c = 62.4 A, but the R factors remain high following initial processing of the data. The data set is twinned and it is thus reprocessed in space group P2, resulting in a significant reduction in the R factors |

| 4.3.3.7 | by the oil-batch method at 291 K, to 2.2 A resolution. Belongs to space group P21 with unit-cell parameters a = 80.5 A, b = 76.5 A, c = 101.9 A, gamma = 106.9 A. The asymmetric unit contains four DHDPS molecules, forming a homotetramer with approximate 222 symmetry. The overall tertiary structure of DHDPS possesses a (beta/alpha)8-barrel fold (TIM barrel) with three additional alpha-helices (alpha9-alpha11) at the C-terminus of the chain. The beta-strands of the barrel form an intrinsic network of hydrogen-bonding interactions with the neighbouring beta-strands and are oriented in the same directions. The functional residue Lys161, which participates in Schiff-base formation, is located within the beta-barrel and the side chain of Tyr132 sits over this residue |

| 4.3.3.7 | complexed with pyruvate, the substrate analogs succinate alpha-semialdehyde and alpa-ketopimelic acid, the inhibitor dipicolinic acid, and the natural feedback inhibitor L-lysine, hanging drop vapor diffusion method, in the presence of beta-octyl glucoside using either potassium phosphate buffer (pH 10) or potassium citrate buffer (pH 7.0) as the precipitant |
