| 2.6.1.16 | crystal structure of intact protein |
| 2.6.1.16 | crystal structure of the isomerase domain in complex with the allosteric inhibitor UDP-GlcNAc and in the presence of glucose 6-phosphate, fructose 6-phosphate and an analogue of the reaction intermediate, 2-amino-2-deoxy-D-mannitol 6-phosphate. Deduction of a solution structure of the native protein. The tetrameric enzyme can be described as a dimer of dimers, with each half similar to the related enzyme from Escherichia coli. The core of the protein consists of the isomerase domains |
| 2.6.1.16 | crystal structures of enzyme alone and in complex with the glucosamine 6-phosphate product at 2.95 A and 2.9 A resolution, respectively. No electron density for the glutaminase domain is observed. Upon sugar binding, the C-terminal loop, which forms the major part of the channel walls, becomes ordered and covers the synthase site. The ordering of the glutaminase domains likely follows fructose 6-phosphate binding by the anchoring of Trp74, which acts as the gate of the channel, on the closed C-terminal loop. This is accompanied by a major conformational change of the side chain of Lys503 of the neighboring synthase domain that strengthens the interactions of the synthase domain with the C-terminal loop and completely shields the synthase site. The concomitant conformational change of theLys503-Gly505 tripeptide places catalytic His504 in the proper position to open the sugar and buries the linear sugar, which is now in the vicinity of the catalytic groups involved in the sugar isomerization reaction |
| 2.6.1.16 | crystals are composed of a trans-acting form of the Thermoanaerobacter tengcongensis ribozyme with a single 2'-deoxyribose substitution at the cleavage site, which traps the RNA in the precleavage state. These crystals yield an accurate structure of the RNA to 1.7 A resolution |
| 2.6.1.16 | docking study using inhibitors 1,1'-[1,3,4-thiadiazole-2,5-diylbis[sulfanediyl(1-oxoethane-2,1-diyl)]]ditetrahydropyridazine-3,6-dione, 2,2'-(1,3,4-thiadiazole-2,5-diyldisulfanediyl)bis[N-(pyrrolidin-1-yl)acetamide]. The binding pocket of the enzyme includes the residues, Cys300, Gly301, Thr302, Ser303, Ser347, Gln348, Ser349, Thr352, Val399, Ser401, Ala602 and Lys603. The high docking energies of all generated conformers of 1,1'-[1,3,4-thiadiazole-2,5-diylbis[sulfanediyl(1-oxoethane-2,1-diyl)]]ditetrahydropyridazine-3,6-dione are strongly proportional to the antibacterial activities |
