S.C.A.R was developed to create, display and manipulate structures of small molecules, proteins and DNA.
Data Input is made either by choosing existing PDB files (from the PDB database) or by the Create utility which enables a user to create polypeptide chains in an extended structure (phi, psi = 180). The user has the ability to interfere with the 3-D structure of the protein altering at will the phi, psi angles of some or all residues. The representation is made using the Chemscape Chime plugin.
The output may be given in graphics or in text mode. To operate the package you need:
