About

The C2Sv2.0 service allows to reconstruct full-atom protein structures based on contact maps. The needed inputs are the protein sequence in a FASTA file (FASTA example) and the contact map in a matrix format (CMAP example).

Methods

C2Sv2.0 is a three-step procedure which uses available bioinformatic applications. First, the 3D coordinates of C-alpha atoms are estimated based on constraints imposed by the contact map (FT-COMAR) (Vassura et al., 2008). This is followed by the backbone reconstruction (REMO) (Li and Zhang) and side-chain modeling (SCWRL) (Krivov et al., 2009).
