 the rigid body produces a large number of
adjacent structures with good surface complementarity, followed by the
rearrangement of the approximation free energy. Fast Fourier Transform (FFT)
related methods (using electrostatic or electrostatic and dissolve terminology
to systematically explore the space of docking conformations (but their
potential is limited to the form of correlation functions) and then use polar
coherence to speed up the search for candidates , But also uses other methods
such as computer vision, Boolean operations, and genetic algorithms. In fact,
the Fourier transform algorithm can also use spherical harmonic decomposition
to speed up the search for the FRODOCK 3D space. To further improve FFT
docking, add atomic contact energy Estimating desolvation energy in RDOCK and
static correction in ZDOCK

There are different sorts of FFT-based
inflexible body-based docking instruments that don’t have a 3D system search,
for example, HEX, which utilizes circular polar directions to translate and
rotate space. Likewise, the proficiency of calculations in view of Fourier
changes is additionally quickened with cutting edge programming bundles, for
example, 3D convolution libraries and new equipment advances, for example,
designs preparing units . The docking program (dot) plays out an efficient
inflexible body system of the atoms and rotate the second molecule. At long
last, the entirety of the intermolecular energies of electrostatic and nuclear
desolvation energies is viably figured as a function of FFT (as the
relationship of the considerable number of results

Like ZDOCK, MEGADOCK uses FFT to
generate docking structures in grid-based 3D space. But MEGADOCK is 8.8 times
faster than ZDOCK because only the shape fraction function is easier

Accuracy of rigid body docking

Docking is considered to be effective if the binding of the
active site to the ligand approaches a given limit to the X-ray . The DOCK
program of aspartic proteases applied to HIV has led to the use of highly
potent candidate inhibitors in clinical practice at levels that are too
low.  for designing more potent inhibtor
this molecule can be used as a lead compound

Coworkers  have
designed protease inhibitors that inhibit schistosomiasis and malaria parasites
that are pathogenic by a function of shape complementarity and by a
simplification of the molecular mechanical potential energy that can interact
with proteases and ligands. The DOT program successfully predicted the electron
transfer of the positively charged cytochrome c electron transport complex on
the cytochrome c oxidase surface formed by subunit II. Of the 25 protein-protein
complexes tested with the BiGGER program, 22 complexes approximated the local
docking geometry with a C-value (RMS) bias of ?4.0A and 14 out of 20 found in
the highest ranked solution molecules A first-class solution for MolFit
programs using geometrical and geometrical static docking, you can identify
near-correct solutions at the interface of disassembled and non-bonded
structures with limited rotational freedom. In the CAPRI (Key Assessment of
Interaction) experiment, GAPDOCK correctly predicted 17 out of 52 contacts with
Goal 1 and 27 out of 52 contacts with other contacts. With PatchDock, 31 out of
35 instances had a lower RMSD of less than 2. Of the 26 examples, the correct
location was the highest, and the other 9 examples were correctly ranked in the
top 30. However, SymmDock can only predict structures that have periodic
symmetry. SymmDock is not suitable for such predictions if the input monomers
have different symmetries in their natural complex

With simple unbound–bound target cases, 47% of the interface
contacts were correctly predicted by ZDOCK, demonstrating its strength in
binding site prediction

66 of 83 solutions were predicted by the latest soft dock
version , 3.307 and 3.224 is the RMSD minimum between experimental structure
and the model . in the docking straategy the ske – dock server delivers an
adequate ligand RMSD of 5 targets for 8 targets .When considering only at least
one acceptable solution to ZDOCK, the conformations in the first 10 and 50
solutions were 69% and 77%.
