Show all pathways known for 3.2.2.30Display the reaction diagram Show all sequences 3.2.2.30enzyme only or in complex with formycin A or adenine, hanging drop vapor diffusion method, using 0.1 M Tris pH 8.5 and 16% (w/v) polyethyleneglycol 8000, at 18°C 716856
Show all pathways known for 3.2.2.30Display the reaction diagram Show all sequences 3.2.2.30hanging drop vapor diffusion method, mutants E14Q (0.1 M HEPES pH 7.5, 25% (w/v) PEG 3350, 0.2 M NaCl), D199N (0.1 M bis-Tris pH 5.5, 25% (w/v) PEG 3350, 0.2 M MgCl2-6H2O) and D199A (0.1 M bis-tris pH 6.5, 25% (w/v) PEG 3350, 0.2 M Li2SO4-H2O) 726595
Show all pathways known for 3.2.2.30Display the reaction diagram Show all sequences 3.2.2.30hanging drop vapor diffusion method. Inactive D198N mutant bound to 5'-methylthioadenosine using 0.2 M magnesium chloride, 0.1 M HEPES (pH 7.5), and 25% (w/v) PEG 3350 727008
Show all pathways known for 3.2.2.30Display the reaction diagram Show all sequences 3.2.2.30structure of apoenzyme at 1.25 A, and five enzyme complexes with transition-state analogues at 1.42 to 1.95 A resolution. Inhibitor binding induces a loop movement to create a closed catalytic site with Asp196 and Ile152 providing purine leaving group activation and Arg192 and Glu12 activating the water nucleophile 749468
Show all pathways known for 3.2.2.30Display the reaction diagram Show all sequences 3.2.2.30structures of wild-type cocrystallized with S-adenosylhomocysteine, formycin A, and (3R,4S)-4-(4-chlorophenylthiomethyl)-1-[(9-deazaadenin-9-yl)methyl]-3-hydroxypyrrolidine as well as one structure of inactive variant D198N cocrystallized with S-adenosylhomocysteine. Mechanism of D198 pKa elevation is through the sharing of a proton with atom N7 of the adenine moiety possessing unconventional hydrogen-bond geometry 752041
Show all pathways known for 3.2.2.30Display the reaction diagram Show all sequences 3.2.2.30wild type and mutant enzymes E14Q, D199N, and D199A, sitting drop vapor diffusion method, using 4.0 M NaH2PO4/K2HPO4 pH 7.0 (wild type), 0.1 M HEPES pH 7.5, 25% PEG 3350, 0.2 M NaCl (E14Q), 0.1 M bis-Tris pH 5.5, 25% (w/v) PEG 3350, 0.2 M MgCl2-6H2O (D199N), and 0.1 M bis-Tris pH 6.5, 25% (w/v) PEG 3350, 0.2 M Li2SO4-H2O (D199A) 726595
