A modular numbering system of selected oligopeptides for molecular computations: using pre-computed amino acid building blocks

A standardized numbering system has been developed to define the relative spatial orientation of all constituent atomic nuclei in model peptide systems. The system is expected to improve efficiency in the formulation of initial structural estimates and analysis of the results emerging from molecular orbital computations on oligopeptides, catalogued in a database. This standard provides each peptide residue with a numeric definition of its own, …
