Abstract

AbstractThe tRNA molecule takes suitable amino acid to the ribosome for the formation of peptide bonds. In starting the peptide chain, the first amino acid which is taken to the ribosome is methionine. We have simulated methionine‐amino acid bonding and amino acid‐tRNA bonding, using a mixed study of quantum mechanics ab‐initio and molecular mechanics. NMR shielding tensors and thermodynamic parameters and total energies are also calculated. It is important to understand the physical properties and the environmental conditions in which the dipeptides cause the tRNA to attach to a wrong amino acid. One of the properties studied is the dielectric environment of in which the bonding occurs. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
