Molecular Geometry Predictions V.P.Gupta, inPrinciples and Applications of Quantum Chemistry, 2016 7.6.2Use of Molecular Symmetry Use ofmolecular symmetryingeometry optimizationhas its good and bad points. The use of symmetry reduces the number of coordinates that must be optimized. The number of ...
aRibbon structure of theAaNGT complexed to UDP and FGNWTT. The N-terminal AAD, the N-terminal Rossmann and C-terminal Rossmann fold subdomains are colored in cyan, yellow and orange, respectively. The UDP nucleotide is depicted with gray carbon atoms whereas the peptide is shown as green car...
An increasing number of GPCRs have been reported to exhibit high basal or constitutive activity in the absence of extracellular stimuli1,2,3,4. The spontaneous manner of GPCRs is implicated in human physiological functions and various disorders5. As a result, inverse agonists have been discovered...

Geometry optimisation calculations using semiempirical molecular orbital and molecular mechanics methods on tetrahedral zinc complexes with derivatives of the amino acids cysteine, histidine and glutamic acid have been performed. Charge interaction terms, based on a semiempirical calculation of partial atomic ...
which is the major component of natural gas, has four bonding pairs of electrons around the central carbon atom; the electron-pair geometry is tetrahedral, as is the molecular structure (Figure 4). On the other hand, the ammonia molecule, NH3, also has four electron pairs associated with the...
