Abstract

With the construction and implementation of a logical and standardized numbering of atomic nuclei, to define mono-, di-, and oligo-peptide systems, automation of input file generation and data extraction could greatly improve the efficiency of the search for the structural energy minima on the potential energy hypersurface of these systems. The internal hierarchy of the database covering constitutional structures, protective groups, levels of theory, and basis sets used, as well as the variety of possible conformations, is also discussed.
