[Biojava-l] classes in biojava able to handle 3D protein structures ???

[Antoine Logean]

Hello,

Are there classes, in the biojava library, that can work with 3D 
coordinates of protein structures (in form of PDB files)? for example: 
transform the cartesian coordinates in internal coordinates, rotate 
dihedral angles of the backbone atoms, the dihedral angles of the side 
chains,  .... and so on ...

Thanks

Antoine
