I have a question about gaps that I will be solving
soon. Why does my Matlab protein structure software
produce this when using pdb4amber:
I am not new to amber, and the coordinates are good in
this file, which I made by rotating phi/psi/chi angles from
a linear structure. Nonplanar because I used dihedral
angles from the PDB model 1 structure to rotate about
the bonds from a linear structure, with amino acid coordinates
from the Cyana lib. There is no issue with PDB files, only
when I rotate angles and create a new pdb file which is in the
format, which I used pdb4format also to check the indentations.
I attached the initial linear peptide 2L3W 143 residue chain which
does not load correctly in pymol although the coordinates are
correct and can be seen. I am using the linear structure to find
the general one by rotating about dihedral bonds phi/psi and chi.
Simply rotating bonds should not cause problems in a pdb file if
done correctly, and certainly not produce gaps; I have checked
bond distances in my 'rotated' protein model. Attaching the
pdb files exceeds the Amber reflector memory limit.
