What is a PDB file extension?

Program database (PDB) is a proprietary file format (developed by Microsoft) for storing debugging information about a program (or, commonly, program modules such as a DLL or EXE). PDB files commonly have a . pdb extension. A PDB file is typically created from source files during compilation.

How do I read a PDB file in Python?

Read PDB files. Write a function readPDBfile(filename) that will read the atoms for a protein stored in pdb file whose name is given as the argument. Your function should return a Python tuple containing 4 values: (anum, aname, resno, coords) . anum should be an array with the serial number for each atom.

What is Biopython used for?

Biopython is a set of freely available tools for biological computation written in Python by an international team of developers. It is a distributed collaborative effort to develop Python libraries and applications which address the needs of current and future work in bioinformatics.

What is ab factor?

Definition. The temperature factor (also called the temperature value, B factor, B value, or Debye-Waller factor) is. “a factor that can be applied to the X-ray scattering term for each atom (or for groups of atoms) that describes the degree to which the electron density is spread out.

What is Debye-Waller effect?

The Debye-Waller factor is the ratio of the coherent scattering or absorption cross section of a photon or electron by particles bound in a complex system to the value for the same process on an analgous free particle. Prime examples are: Bragg scattering, the Mössbauer effect and related phenomena at zero temperature.

What is structure factor of a crystal?

The crystal structure factor gives the amplitude and phase of a diffracted wave from a crystal. The factor is determined by the atom species and their positions in a unit cell.

How is Debye-Waller factor calculated?

The Debye-Waller factor is directly related to the atomic displacement parameter through a geometric scaling term; B = 8π2U.

What is the Debye temperature?

: the temperature at which the atomic heat of a pure cubic crystal equals 5.67 calories per gram atom per degree. — called also characteristic temperature.

What is a temperature factor?

The temperature factor indicates how much an atom oscillates or vibrates around the position specified in the model. In other words, it’s a measure of the thermal motion of individual atoms in the crystal.

What is overall B factor?

In the isotropic case, it adds the refined B-factor shift to the B array and it also applies the B-factor shift to the structure factors. In the anisotropic case, the overall isotropic contribution is subtracted from the tensor such that the trace of B is zero.

How is B factor calculated?

For example: The temperature of the md simulation was set at 298K. The B-factor at 298 K was calculated from RMSF by the formula: B = 8*Pi*Pi*(RMSF)**2/3 .

What is b factor in Pymol?

B-factors indicates the mobility (displacement) of the atoms. This displacement may be because of temperature-dependent vibrations or static disorder in a crystal lattice. Displacement has a direct relationship with flexibility i.e. more flexibility in the atom, larger will be the displacement or more will be B-factor.

What is a good B factor crystallography?

A good model should show average devations from expected values of no more than 0.2 angstroms in bond lengths and 4 degrees in bond angles. Another result of crystallographic structure determination is a number called a B-factor or temperature factor for each atom.

What is occupancy in PDB file?

The occupancy value is used to indicate the fraction of molecules that have each of the conformations. Two (or more) atom records are included for each atom, with occupancies like 0.5 and 0.5, or 0.4 and 0.6, or other fractional occupancies that sum to a total of 1.

What is a protein B-factor?

Abstract. The term B-factor, sometimes called the Debye-Waller factor, temperature factor, or atomic displacement parameter, is used in protein crystallography to describe the attenuation of X-ray or neutron scattering caused by thermal motion.

What is Rmsd value?

The rmsd value gives the average deviation between the corresponding atoms of two proteins: the smaller the rmsd, the more similar the two structures. Efficient algorithms have been developed to find the best orientation of two structures that gives the minimal possible rmsd [2], [3].

How is Autodock Rmsd calculated?

To do so, open both the original and redocked conformations into Autodock Tools, right click on one of them in the control panel, then click on RMSD/Superimpose.

What is cluster Rmsd?

Cluster RMS is the root mean square difference in coordinates between this conformation and the cluster reference. Reference RMS is the rms difference between this structure and the input structure.
