Crystal structure of UDP-N-acetylmuramoyl-L-alanyl-D-glutamate: meso-diaminopimelate ligase from Escherichia coli.
UDP-N-acetylmuramoyl-l-alanyl-d-glutamate:meso-diaminopimelate ligase is a cytoplasmic enzyme that catalyzes the addition of meso-diaminopimelic acid to nucleotide precursor UDP-N-acetylmuramoyl-l-alanyl-d-glutamate in the biosynthesis of bacterial cell-wall peptidoglycan. The crystal structure of the Escherichia coli enzyme in the presence of the final product of the enzymatic reaction, UDP-Mu...
متن کاملTheoretical investigations on molecular structure, NBO, HOMO-LUMO and MEP analysis of two crystal structures of N-(2-benzoyl-phenyl) oxalyl: A DFT study
The N-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. The quantum theoretical calculations for two crystal structures of N-(2-benzoyl-phenyl) oxalyl (compounds I and II) were performed by Density Functional Theory (B3LYP method and 6-311+G* basis set). From the optimized structures, geometric paramet...
متن کاملCrystal structure of O-benzyl-l-tyrosine N-carboxy anhydride
In the title compound, C17H15NO4 (alternative name; O-benzyl-l-tyrosine N-carb-oxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benz-yloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°, and are inclined to the oxazolidine ring by 59.16 (11) and 58.42 (11)°, respectively. In the crystal, mol-ecules are linked by N-H⋯O and C-H...
متن کاملCrystal structure of dipotassium N-carbodithioato-l-prolinate trihydrate
The mol-ecular and crystal structure of the l-proline-derived di-thio-carbamate-carboxyl-ate compound poly[tri-μ-aqua-(μ-2-carboxyl-atopyrrolidine-1-carbodi-thio-ato)dipotassium], [K2(C6H7NO2S2)(H2O)3] n or K2(SSC-NC4H7-COO)·3H2O, has been determined. The di-thio-carbamate moiety displays a unique coordination mode, comprising a 'side-on' π-coordinated K+ cation besides a commonly σ-chelated K+...
متن کاملCrystal structure of γ-methyl l-glutamate N-carboxy anhydride
In the title compound, C7H9NO5, alternative name N-carb-oxy-l-glutamic anhydride γ-methyl ester, the oxazolidine ring is essentially planar with a maximum deviation of 0.020 (3) Å. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds between the imino group and the carbonyl O atom in the methyl ester group, forming a tape structure along the a-axis direction. The tapes are linked by C-...
