All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem that the operation difficulty is large due to the fact that a command line script needs to be called manually when a visual platform is adopted for molecular docking in the prior art, so that the learning cost of software is reduced, and the molecular docking technology can better serve drug research and development, the invention provides a molecular docking method based on an Autodock visual platform, which is based on the Autodock and is added with an intelligent and automatic processing flow, and the method converts structure files in various formats uploaded by a user into a PDBQT format special for the Autodock Vina by automatically processing input files; automatically judging the geometric information of the original ligand in the macromolecule, and using the information for molecular docking; the macromolecular structure is automatically pretreated, so that the macromolecular structure can be directly used for molecular docking; the output results of the molecular docking are automatically analyzed, so that a user can conveniently check the conformation of each molecule and the potential receptor-ligand interaction, thereby opening up all links of the molecular docking and providing a one-stop solution of the molecular docking.
Referring to fig. 1, fig. 1 is a flowchart of a molecular docking method based on an AutoDock visualization platform according to the present invention.
In a specific embodiment, the molecular docking method based on the AutoDock visualization platform provided by the invention is applied to the back end of the visualization platform, and the method comprises the following steps:
s101: structural information of the ligand molecule and structural information of the receptor molecule are obtained. In a specific use scenario, the user interface is implemented based on a web, provides an upload button to a user, and supports storage formats of various common chemical structures including PDB and MOL. The user uploads an original file to be used to the server without any conversion operation in advance, and the original file contains the structural information of the ligand molecules and the structural information of the receptor molecules.
S102: and generating ligand input information in a preset format according to the structural information of the ligand molecules, and generating receptor input information in a preset format according to the structural information of the receptor molecules, wherein the preset format is a PDBQT format recognizable by the Autodock. After the structural information of the ligand molecules is obtained, an Autodock Tools plug-in a visual platform can be directly called to convert the Autodock Tools plug-in into a PDBQT format, so that ligand input information is generated. For receptor molecules (i.e. macromolecular proteins), after acquiring the structural information, the receptor molecules need to be preprocessed, converted into the PDBQT format, and used as receptor input information.
Specifically, the proteins used for molecular docking often need to be processed to enter the docking step, for example, original ligands and water molecules in the proteins need to be removed, in this embodiment, automatic processing of non-amino acid residues in the structure is realized by removing atoms marked by the hettm field in the PDB file, so as to obtain a receptor file completely composed of amino acids, and then hydrogenation and charging operations are performed by calling Autodock Tools for the proteins, and the processed proteins are stored in the PDBQT format, so as to generate receptor input information for the subsequent docking step.
S103: generating at least one molecular docking result based on the ligand input information, the receptor input information, and the docking parameters in response to the inputted docking parameters. In the actual use process, if a plurality of small molecules (namely ligands) are uploaded by a user, each small molecule and a macromolecule (namely a receptor) are docked circularly, a molecule docking result is generated after each docking, the plurality of small molecules can obtain a plurality of molecule docking results, and if the plurality of macromolecules are uploaded, the first macromolecule read by a program is used as the receptor.
S104: and generating an output file according to each molecular docking result, and outputting the output file so as to display the output file at the front end of the visual platform.
Specifically, after corresponding receptor and ligand files are processed, an Autodock Vina program is called in the background, and the files and parameters are input into the Autodock Vina program, so that an original output file of the Autodock Vina is obtained. The original output file is the conformation of the small molecule ligand, wherein no inter-atom bonding information exists, the bonding information stored in the input file uploaded by a user is read, the corresponding relation of atoms between the input file and the output file is established through atom coordinates, chemical bonds are added to the atoms in the output file, the small molecule ligand and protein are combined into a PDB file, different small molecule conformations are distinguished by MODEL fields in the PDB file, and the whole file is transmitted back to the front end.
Furthermore, before molecular docking, a search area can be obtained, and by locking the search area, the processing quantity of data is reduced, and the data processing efficiency is improved. After a user uploads a file (PDB format) storing protein, a background analyzes the file, extracts all atoms marked as HETATM by traversing all atom records in the file, records the residue names and numbers of the atoms, and transmits the information serving as potential ligand information back to a web interface. After a user selects a certain ligand according to actual needs of the user, the software sends a request to the server again, the server analyzes boundary information (namely xmin, xmax, ymin, ymax, zmin and zmax) of the ligand according to Cartesian coordinates of all atoms in residues in a PDB file according to the name of the ligand selected by the user, converts the boundary information into Cartesian coordinates of a central point and the geometric dimension of the ligand, transmits the converted information to a web interface, and uses the converted information as receptor input information for subsequent docking operation.
In some embodiments, as shown in fig. 2, generating at least one molecular docking result based on the ligand input information, the receptor input information, and the docking parameters in response to the inputted docking parameters further comprises:
s201: judging the state of the molecular docking result based on a preset judgment rule; wherein the state of the molecular docking result comprises docking success or docking failure. If Autodock Vina does not find any one of the possible conformations, or if the binding energy of the first ranked conformation is positive, docking failure is indicated, otherwise docking success is indicated.
S202: and processing the molecular docking result according to the state of the molecular docking result, and generating the output file based on the processed molecular docking result. That is to say, when the docking success or the docking failure is the result of the molecular docking, the subsequent steps taken are different, so that the accuracy of the result output is further improved, and after the docking failure, no other calculation operation is needed, so that the calculation amount of the system is reduced.
Specifically, if the molecular docking result is determined to be successfully docked, calculating the molecular parameters of the ligand molecules, such as the molecular weight, molecular formula, ring number, hydrogen bond donor number, hydrogen bond acceptor number, logP property, TPSA property, and Lipinski property of the ligand molecules, to obtain ligand parameter information, and reconstructing the chemical bonds of the ligand molecules;
and combining the ligand parameter information, the ligand molecules after chemical bond reconstruction and the receptor molecules to be used as the molecular docking result, and forming an output file.
And judging that the state of the molecular docking result is a docking failure, taking the ligand input information and the receptor input information as the molecular docking result, and forming an output file.
In order to improve the display effect of the output file and improve the display intuitiveness and visibility, as shown in fig. 3, the invention also provides a molecular docking method based on an AutoDock visual platform, which is applied to the front end of the visual platform, and the method comprises the following steps:
s301: acquiring an output file, and displaying the output file in an image form;
wherein the output file is generated according to the molecular docking result; the molecular docking result is generated by the back end of the visualization platform in response to the inputted docking parameters based on the ligand input information, the receptor input information and the docking parameters; the ligand input information is information in a preset format generated according to the structure information of ligand molecules; the receptor input information is information in a preset format generated according to structural information of receptor molecules.
Specifically, the conventional application method of Autodock Vina can only obtain the conformation of the small molecule after docking, and the interaction between the small molecule and the ligand cannot be observed. According to the invention, by integrating the molecule display engine mol, the molecule structure returned from the rear end is directly displayed on the web page, and a user can switch different small molecule conformations through a mouse. After the small molecule structure displayed in mol is clicked by the left key, the program can focus and display the small molecule, and automatically analyze the potential interaction between the small molecule and the protein, including hydrogen bond, hydrophobic interaction, pi-pi interaction, salt bridge and the like, so that a user can conveniently evaluate the binding capacity between the butted small molecule and the protein.
As shown in fig. 4, a specific usage scenario is taken as an example below to briefly describe an operation process of the molecular docking method based on the AutoDock visualization platform provided by the present invention.
1. The user uploads the small molecules and the large molecules, and the program analyzes the names of the non-standard residues contained in the large molecule file for the user to select. After the user clicks on the residue name, the program automatically analyzes the position and size of the residue and automatically fills the corresponding input box.
2. And clicking a submission button by the user, and submitting the task to the background for calculation. The background program can traverse all the input files, and automatically judge whether the current molecule is a macromolecule or a micromolecule according to the molecular weight, wherein the threshold value of the molecular weight is 3000. When the macromolecule is judged, calling Autodock Tools to carry out macromolecule pretreatment, carrying out operations of hydrogenation, charge addition and nonstandard residue removal, and storing the pretreated macromolecules as a PDBQT format; otherwise, if the structure is judged to be a small molecule, the Autodock Tools are called to directly convert the structure into a PDBQT format. Preparing macromolecules and micromolecules for butt joint, calling an Autodock Vina program, inputting the structure file and butt joint parameters, and carrying out butt joint calculation. If the user uploads a plurality of small molecules, each small molecule is in butt joint with the large molecule in a circulating mode; if multiple macromolecules are uploaded, the first macromolecule read by the program is used as the receptor.
3. If the Autodock Vina does not find any possible conformation, or the binding energy of the first ranked conformation is a positive value, the molecule is judged to have butt joint failure, and the molecule is counted into a failure set without any treatment; otherwise, recording the successful set, calculating the molecular weight, molecular formula, ring number, hydrogen bond donor number, hydrogen bond acceptor number, logP, TPSA and Lipinski properties of the molecule, reconstructing the chemical bond of the molecule, and combining the chemical bond with the acceptor into a file.
4. And transmitting the butted structure to a user, and checking the 3D combination mode and the 2D interaction diagram of the macromolecules and the micromolecules by clicking the record of a certain molecule by the user.
