A PDB (Protein Data Bank) file is a standard file format used to store information about the three-dimensional structure of biological molecules, particularly proteins and nucleic acids. It contains detailed atomic coordinates, information about the chemical structure of the molecules, and metadata such as the experimental methods used to determine the structure. The PDB format is crucial in the field of structural biology, providing a standardized way to share and disseminate structural data. Researchers can use PDB files to visualize and analyze the spatial arrangement of atoms in a molecule, aiding in understanding its function and interactions with other molecules.

PDB files are typically generated through experimental techniques like X-ray crystallography, nuclear magnetic resonance (NMR), or electron microscopy. Each atom in the molecule is represented by its coordinates in three-dimensional space, and additional information such as atom types, bond lengths, and angles is included. This wealth of data allows scientists to create accurate visualizations of molecular structures, supporting various applications in drug discovery, biomolecular engineering, and understanding the fundamental processes of life at the molecular level. The PDB is a global repository, and its files are freely accessible, fostering collaboration and accelerating progress in structural biology.

In addition to atomic coordinates, a PDB file may also contain information about the experimental conditions, references to relevant scientific literature, and annotations that describe specific features of the molecule. Various software tools and databases support the retrieval, visualization, and analysis of PDB files, making them a fundamental resource for researchers across diverse scientific disciplines. The format has evolved over time to accommodate the growing complexity of structural data, and it continues to play a pivotal role in advancing our understanding of the intricate structures that underlie the functions of biological macromolecules.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

Information for converting from PDB to OBJ

Your PDB file will be converted to a OBJ file using our unified 3D model and mesh conversion tool. Our PDB 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As PDB supports color materials and OBJ does not, our tool will not attempt to transfer any color information, your final 3D model will contain geometry data only.
