Hello,

Given a list of PDB codes (for kinases), I would like to calculate the phi torsion angle for the residue D in the sequence pattern "DFG", which is a sequence that is very conserved in kinases. Would you know how to do that? Here is in attachment a small list of PDB codes with the measured value for the phi angle.  I am having trouble finding the correct values, especially when there are missing residues at the beginning of the protein file (PDB code 2H8H in the list in particular).

Additionnally, how to do that with a sequence pattern like [LIVMFYC] - {A} - [HY] - x - D - [LIVMFY] - [RSTAC] - {D} - {PF}  - N -  [LIVMFYC](3) , to caculate the torsion angle for the residue [RSTAC]?

Thank you very much in advance for your help!
