From bioinformatics to database mining and form molecular modelling to applied quantum chemistry our techniques in use cover a wide range of methodology. We are conducting conformational analysis, spectral property calculations (e.g. IR, NMR), energy distribution and potential energy calculations of alpha- and beta-amino acid residues, peptides and proteins. Depending on their size ab initio or MM and MD methods are routinely used. In addition, we parameterize force fields, design new algorithms or even make a standalone software (e.g. CCA+) depending on the scientific topic to be solved.

  • Long, longer, perhaps the longest helix and sheet by QM

    We are pleased to inform you that our most recent manuscript entitled “Helix compactness and stability: electron structure calculations of conformer dependent thermodynamic functions” Jákli et al. is now accepted for publication in Chemical Physics Letters. Congratulations to all contributors!
