BRAGI is an interactive protein-modelling program. It was developed for the special purpose to modell unknown proteins from the structure of a known one. But it has many other features like:

  • Display of proteins or non-proteins; Different file formats (Brookhaven, RDI, Sybyl MOL2)
  • Display of structures in various modes (space filling, Ball&Stick, tube, ...)
  • Display in stereo mode
  • Calculation and display of the molecular surface (coloured by electrostatics or hydrophobicity; solid or wireframe)
  • Calculation and display of secondary structure
  • Display of backbone torsion angles (RAMACHANDRAN-Plot)
  • Exchange of amino acids & variation of torsion angles with interactive energy calculation
  • Comparison of the three dimensional structure and supercomposition of two molecules by RMS fitting
  • Calculation of covalent and potential hydrogen bonds
  • Building or replacing protein loops
