| 2.4.1.38 | catalytic domain of R228K-Gal-T1 and mouse recombinant alpha-lactalbumin are cocrystallized in the presence of UDP-galactose and MnCl2. Crystals are grown at room temperature by the hanging drop method. Crystal structure of R228K-Gal-T1 complexed with alpha-lactalbumin, UDP-galactose, and Mn2+, determined at 1.9 Å resolution shows that the Asp318 side chain exhibits a minor alternate conformation, compared to that in the wild type |
| 2.4.1.38 | crystal structure of enzyme-alpha-lactalbumin complex with UDP-Glc |
| 2.4.1.38 | crystal structures of the beta4galactosyltransferase catalytic domain and its complex with uridine diphosphogalactose |
| 2.4.1.38 | mutant enzyme M340H/C338T in complex with Glc-NAcbeta1-3Galbeta-O-naphthalenemethanol, hanging drop vapor diffusion method, using MES-NaOH buffer (pH 6.0), 1.5 M ammonium sulfate, and 3% dioxane |
| 2.4.1.38 | purified recombinant M340H-Gal-T1 mutant in the open conformation as apo-enzyme, and its Mn2+ and Mn2+-UDP-Gal-bound complexes, hanging-drop vapor diffusion method using a protein solution at 10 mg/ml concentration with a precipitant containing sodium citratebuffer, pH 5.5, and 10% w/v PEG-4000, the crystals of the Mn2+ complex are grown in the droplet containing 10 mM MnCl2, while the crystals containing UDP-Gal and Mn2+ are grown in the presence of 17 mM each of MnCl2 and UDPยGal, X-ray diffraction structure determination and analysis at 1.7-2.0 A resolution |
| 2.4.1.38 | purified recombinant pentenary complex of bovine M344H-Gal-T1 mutant-Mn2+-UDP-GalNAc-Glc-alpha-lactalbumin, hanging-drop vapor diffusion method, using 20 mg/ml of beta-M344H-Gal-T1 and 10 mg/ml of mouse alpha-lactalbumin in the presence of 10 mM each ofUDP-Gal and CaCl2, with the precipitant containing 100 mM NaCl, 100 mM Mes-NaOH buffer, pH 6.0, and 12.5% PEG 4000, the crystals of the complex cannot be obtained in the absence of CaCl2, X-ray diffraction structure determination and analysis at 1.9-2.0 A resolution |
| 2.4.1.38 | purified wild-type and M340H mutant enzymes in complex with pentasaccharide GlcNAcbeta1,2-Manalpha1,6 (GlcNAcbeta1,2-Manalpha1,3) and trisaccharide GlcNAcbeta1,4-GlcNAcbeta1,4-GlcNAc substrates, X-ray diffraction structure determination and analysis at 1.9-2.0 A resolution |
| 2.4.1.38 | recombinant enzyme, crystal structure of lactose synthase reveals a large conformational change in its catalytic component, the beta1,4-galactosyltransferase-I |
