In fact, the ATP binding pocket of 1atp,E is an open cavity, while the ATP binding pocket of 1atp,EI is an internal cavity.
Hence, the two surfaces are different and the optimal alignment between the ATP binding pockets of 1atp,EI (both chains) and of 1csn,A is slightly different from the optimal alignment between the ATP binding pockets of 1atp,E (only one chain) and of 1csn,A ( Figure 7 ).
The list of other structures must belong to the PDB, and the user can specify the chain(s) using the syntax pdb_id,chain(s) (e.g. 1atp, EI).
In this example, the solution of the comparison between 1atp,EI and 1csn,A contains only corresponding atoms from chain E on structure 1atp.
The surface determination routine scales linearly with the number of atoms, ranging from a few seconds for ordinary structures (e.g. 1atp, chain E) to minutes for huge macromolecular complexes (e.g. 1aei, all chains).

It was shown that replacement of Arg19 of the inhibitory peptide (at position P−2, experimentally shown to bind at the −2 subsite (PDB code 1ATP)) by Gly reduces the inhibition by 520-... old, while similar Arg replacement at the equivalent P−3 position (Arg18) reduces the inhibition by only 90-fold  .
Moreover, the PKA-PKI complex is similarly formed with  (PDB code 1ATP) or without  (PDB code 1APM) the ATP molecule, even though in the former case, the guanidino group of the P−3 Arg is hydrogen-bonded to the ATP ribose.

Modelling of the substrate peptide (grey ribbon) and ATP-MgCl 2 (pink stick and ball) from the PKA structure (PDB code 1ATP) into GAK suggests a suitable pocket for accommodation of a substrate peptid... for phosphorylation.
Superimposition of the PKA–ATP–peptide complex (PDB code 1ATP) revealed that a docking groove created within the active site of GAK would be suitable to accommodate a peptide substrate ( Figure 3 D), which therefore suggests that this conformation of the activation segment may serve as an active conformation of the enzyme to enable peptide binding.
