The 3D format is similar as the standard PDB format but two more columns are added from the template sequences, e.g.
ATOM 2001 CA MET 1 41.116 -30.727 6.866 129 THR ATOM 2002 CA ALA 2 39.261 -27.408 6.496 130 ARG ATOM 2003 CA ALA 3 35.665 -27.370 7.726 131 THR ATOM 2004 CA ARG 4 32.662 -25.111 7.172 132 ARG ATOM 2005 CA GLY 5 29.121 -25.194 8.602 133 ARG Column 1 -30: Atom & Residue records of query sequence. Column 31-54: Coordinates of atoms in query copied from corresponding atoms in template. Column 55-59: Corresponding residue number in template based on alignment Column 60-64: Corresponding residue name in templateThe FASTA format is similar as the standard FASTA format except that the 3D structure is attached after the sequence alignemnts. e.g.
