Usage of pdb2adf

Short description

The program works interactively, and should be straightforwardly to use. However, for some of the stages in the output a short description is given below.

                                  P D B 2 A D F - program
                                     version 2005.01
                              Written by: Marcel Swart, 2005

                         This program uses AMBER parameter files
                            see: http://amber.scripps.edu

Do you want a logfile to be written (Y/n) ?

This option exists to create a logfile of what pdb2adf does. However, it should normally be used only for debugging purposes.

Ignoring atom on line:
ATOM    974   OH LYS A 128     -10.073 42.775 15.690 1.00 38.79     5AZU1065

This is a warning that the atom on that particular line is ignored, should normally occur only few times (less than ten). Depends also on how well the PDB file follows the PDB format rules.

Data Processed:
     Nat:       2519
    Nmol:        196
 NChains:          1

Information about what has been read on the PDB file: the total number of atoms (Nat), number of molecules/residues (Nmol) and number of protein chains (Nchains).

Please wait, making connection tables

At this point, the connections between the atoms are being made by looking at atom distances. It may take a while, depending on the size of the system.

Do you want to make separate files for each chain (Y/n) ?

You have the option to make different inputfiles for different protein chains, but you can also make one inputfile for all of them together.

Found the following terminal amino acid residues : (C-term) 128 (N-term) 1
Do you want to use these as terminal residues (Y/n) ?

Info is given about the C- and N-terminal residue of each chain. Reported for making sure they are chosen correctly. Note, if the C- and N-terminal residues are connected (rarely the case probably), enter N here.

  1   HID   Histidine Delta Hydrogen
  2   HIE   Histidine Epsilon Hydrogen
  3   HIP   Histidine E & D Hydrogens

Suggested option: 0

For a number of residues (His, Glu, Asp, Lys and Cys) there is more than one option available in the AMBER95 force field, depending on the protonation state (His, Glu, Asp and Lys) or the existence of a sulphur bridge/connection to a metal atom (Cys). The default is to choose a different option for the His and Cys residues, and use one option for Glu, Asp and Lys (fully charged). However, if wanted you can make a choice for all residues.

Suggestion: 3

The options for Cys3 are given, with information about the atoms bonded to the SG sulphur atom (on the left), as well as the closest five non-bonded atoms (on the right). This information may help you decide which choice to make for this particular residue. Also given (on the bottom) is the suggested choice, which is based, in this case, on the presence of a sulphur bridge.

Suggestion: 2

For His residues, the information is given for both the delta- and the epsilon nitrogen atoms. Also indicated (by HB) is the presence of a hydrogen bond with another atom. The definition used here is that two atoms are hydrogen bonded if they are both non-carbon/non-hydrogen atoms, and the distance between them is less than the sum of the van der Waals radii of the atoms. It is a simple definition, but seems to be effective. In this case, as the N(delta) is bonded to copper, the proton should be attached to the N(epsilon).

Making choice for which molecules should be QM, which MM

Now we come to the part where the division in the QM and MM systems is made.

Residues belonging to chain  0
Option  Molecule    Option  Molecule    Option  Molecule    Option  Molecule    Option  Molecule
     1: ALA    1        28: GLN   28        55: ASP   55        82: ALA   82       109: ALA  109

etc

All molecules/residues belonging to chain 0 are given, with an option number.

Give option number of molecules to be put in QM region (or 'c' to continue):
Note: by specifying a negative number a molecule is removed from the QM region

Here you are asked to enter the option numbers of the residues you want to put in the QM system.

Putting GLY   45 in QM region
Putting HIS   46 in QM region

In this case, Gly45 and His46 have been put in the QM system.

Make a choice for the QM/MM treatment of GLY   45
 0:  Put completely in QM region
 1:  Cut off at C-alpha (put NH in QM region, CO in MM region)
 2:  Cut off at C-alpha (put NH in MM region, CO in QM region)
 3:  Cut off at C-alpha (put NH and CO in MM region)
 4:  Cut off at C-alpha (put NH and CO in QM region,  sidechain in MM region)
 5:  Put only part of sidechain in QM region

Suggestion: 2
Give choice:

A choice should be made for where to cut-off the QM system. Normally this is done at the C(alpha) position, and you should simply choose the Suggestion.

Give the number of the molecule to be put in QM region (or 'c' to continue):

Also water molecules can be put in the QM system.

Box Shape options:
 1  Spherical box
 2  Cubic box
Make a choice:

Type of box to be used.

Maximum atomic distance (Angs) from center       25.62
Give boxsize (def.:    28.62 Angs)

Size of box to be used to put a layer of solvent molecules around the system. Max. dist. is the maximal distance of any protein atom from the center of mass of the protein. Usually you should choose a boxsize at least 6 Angstrom larger (so at least two solvent molecules are surrounding the system).

Writing inputfile for chain   1

A total amount of 7635 atoms (2545 water molecules) has been added.

Inputfile(s) written, everything processed, work has been done.
Thank you for using the PDB2ADF program.

================================
Normal ending of PDB2ADF program
================================

ADF inputfile(s) have been written, the PDB-file has been processes. Everything is done.

An example on protein structure

The idea of this example is to make an adf-input file using a PDB of an azurin (1DYZ.pdb). The result of this example should be that in the adf-input file the active site of azurin (Figure 1) is in the QM part, and the rest of the protein is in the MM part, and that the solvent water is added (in a box), which is also in the MM part.

An example on solvent shell run

The idea of this example is to make an adf-input file using a PDB file of water (hoh.pdb), in the solvent methanol. The water molecule in the adf-input file should be in the QM part, and the solvent methanol (in a box) is in MM part.

The file is not given completely, since it contains more than 800 atoms. Note that the NEWQMMM format is used if the environment variable SCM_PDB2ADF is set to NEW. This example uses the default ‘old’ QM/MM input style.
