Both protein-sequence specific models rival the predictions generated by programs such as AlphaFold3 (<strong>Figure 1<\/strong>). We integrate these programs in our <a href=\"https:\/\/www.boltzmannmaps.com\/documentation\/import\">&#8220;Choose Protein&#8221; window<\/a>. From there, there is a &#8220;Protein Folding&#8221; tab where there are a variety of options to control in the users&#8217; workflow. (<strong>Figure 2<\/strong>). Benchmarking internally has shown success in a variety of use cases incorporating ligands and ions. The alignment scores perform very well against well-annotated PDB structures. Additionally, since the simulations have similar run times to that of docking methods they can be used as an orthogonal method for docking pose generation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"943\" height=\"1024\" src=\"https:\/\/www.boltzmannmaps.com\/blog\/wp-content\/uploads\/2025\/03\/Screenshot-2025-03-27-at-9.29.51\u202fAM-943x1024.png\" alt=\"\" class=\"wp-image-420\" srcset=\"https:\/\/www.boltzmannmaps.com\/blog\/wp-content\/uploads\/2025\/03\/Screenshot-2025-03-27-at-9.29.51\u202fAM-943x1024.png 943w, https:\/\/www.boltzmannmaps.com\/blog\/wp-content\/uploads\/2025\/03\/Screenshot-2025-03-27-at-9.29.51\u202fAM-276x300.png 276w, https:\/\/www.boltzmannmaps.com\/blog\/wp-content\/uploads\/2025\/03\/Screenshot-2025-03-27-at-9.29.51\u202fAM-768x834.png 768w, https:\/\/www.boltzmannmaps.com\/blog\/wp-content\/uploads\/2025\/03\/Screenshot-2025-03-27-at-9.29.51\u202fAM.png 1365w\" sizes=\"(max-width: 943px) 100vw, 943px\" \/><figcaption class=\"wp-element-caption\"><strong>Figure 2<\/strong>: Protein Folding window in BMaps.

These structural ions and other cofactors assist in predicting more biologically relevant structures.<\/p>\n\n\n\n<p>With AI protein folding, atoms are mapped to coordinates without secondary structure information and does not store bond order information or implicit hydrogens so the default output from the folding programs require significant preparation before the structures are ready for modeling. BMaps however integrates secondary structure assignments and properly assigns valences and adds hydrogens, making the structures ready for modeling tasks. This is all done automatically on our servers, so the user does not have to go through these difficult tasks. Correct protein and ligand structure predictions allow users to maintain a seamless workflow all in BMaps.<\/p>\n\n\n\n<p>Structure-based design has a new tool in the toolbox for scientists of all levels, easily integrated into BMaps. Use cases for Boltz-1 or Chai-1 can both: lead to structure predictions in which there are no experimental structures, or for alternate poses for a ligand where there are known structures. The utility of these programs unified within BMaps allows for users to have a one-stop-shop for drug design.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>References<\/strong><\/h4>\n\n\n\n<p>[1] Abramson, J., Adler, J., Dunger, J., Evans, R., Green, T., Pritzel, A., Ronneberger, O., Willmore, L., Ballard, A.
