Title: Purification, crystallization and preliminary X-ray diffraction studies of d-tagatose 3-epimerase from Pseudomonas cichorii

Abstract

Recombinant d-tagatose 3-epimerase from P. cichorii was purified and crystallized. Diffraction data were collected to 2.5 Å resolution. d-Tagatose 3-epimerase (D-TE) from Pseudomonas cichorii catalyzes the epimerization of various ketohexoses at the C3 position. The epimerization of d-psicose has not been reported with epimerases other than P. cichorii D-TE and d-psicose 3-epimerase from Agrobacterium tumefaciens. Recombinant P. cichorii D-TE has been purified and crystallized. Crystals of P. cichorii D-TE were obtained by the sitting-drop method at room temperature. The crystal belongs to the monoclinic space group P2{sub 1}, with unit-cell parameters a = 76.80, b = 94.92, c = 91.73 Å, β = 102.82°. Diffraction data were collected to 2.5 Å resolution. The asymmetric unit is expected to contain four molecules.

  • A putative UDP-N-acetyl-d-mannosamine dehydrogenase from P. horikoshii OT3 has been crystallized in space group P2{sub 1}, with unit-cell parameters a = 80.28, b = 69.24, c = 83.10 Å, β = 114.4°. X-ray diffraction data have been collected to 1.80 Å resolution. A putative UDP-N-acetyl-d-mannosamine dehydrogenase from Pyrococcus horikoshii OT3, an essential enzyme for polysaccharide biosynthesis, has been overexpressed in Escherichia coli and purified. Crystals were obtained using the oil-microbatch method at 291 K. A native data set extending to 1.8 Å resolution has been collected and processed in space group P2{sub 1}. Assuming the presence of a dimer inmore » the asymmetric unit, the V{sub M} value is calculated to be 2.3 Å{sup 3} Da{sup −1}, which is consistent with the result of a dynamic light-scattering experiment that shows a dimeric state of the protein in solution.« less
  • Two outer membrane factor family proteins, OprM and OprN, from a tripartite efflux pump found in P. aeruginosa were crystallized. A diffraction data set was collected to 3.8 Å resolution in the space group C2 for OprM crystals.
  • The trehalulose synthase MutB from P. mesoacidophila MX-45 has been crystallized in two different crystal forms and diffraction data have been collected to 1.6 and 1.8 Å, respectively. The trehalulose synthase (MutB) from Pseudomonas mesoacidophila MX-45, belonging to glycoside hydrolase family 13, catalyses the isomerization of sucrose to trehalulose (α-d-glucosylpyranosyl-1,1-d-fructofuranose) and isomaltulose (α-d-glucosylpyranosyl-1,6-d-fructofuranose) as main products and glucose and fructose in residual amounts from the hydrolytic reaction. To date, a three-dimensional structure of a sucrose isomerase that produces mainly trehalulose, as is the case for MutB, has been lacking. Crystallographic studies of this 64 kDa enzyme have therefore been initiatedmore » in order to contribute to the understanding of the molecular basis of sucrose decomposition, isomerization and of the selectivity of this enzyme that leads to the formation of different products. The MutB protein has been overexpressed, purified and crystallized using the hanging-drop vapour-diffusion method. Two different crystal forms have been obtained: one diffracts X-rays to 1.6 Å resolution using synchrotron radiation and belongs to space group P1, with unit-cell parameters a = 63.8, b = 72.0, c = 82.2 Å, α = 67.5, β = 73.1, γ = 70.8°, while the other form diffracts to 1.8 Å resolution using synchrotron radiation and belongs to space group P2{sub 1}, with unit-cell parameters a = 63.7, b = 85.9, c = 119.7 Å, β = 97.7°. A molecular-replacement solution has been found using the structure of the isomaltulose synthase (PalI) from Klebsiella sp. LX3 as a search model.« less
  • Recombinant l-rhamnose isomerase from P. stutzeri has been crystallized. Diffraction data have been collected to 2.0 Å resolution. l-Rhamnose isomerase from Pseudomonas stutzeri (P. stutzeril-RhI) catalyzes not only the reversible isomerization of l-rhamnose to l-rhamnulose, but also isomerization between various rare aldoses and ketoses. Purified His-tagged P. stutzeril-RhI was crystallized by the hanging-drop vapour-diffusion method. The crystals belong to the monoclinic space group P2{sub 1}, with unit-cell parameters a = 74.3, b = 104.0, c = 107.0 Å, β = 106.8°. Diffraction data have been collected to 2.0 Å resolution. The molecular weight of the purified P. stutzeril-RhI with amore » His tag at the C-terminus was confirmed to be 47.7 kDa by MALDI–TOF mass-spectrometric analysis and the asymmetric unit is expected to contain four molecules.« less
