Current computational methods rely on the assumption that\u0000the binding pose of the target molecule is known, which is not always feasible,\u0000as conformations of novel targets are often unknown and tend to change upon\u0000binding. In this work, we formulate proteins and molecules as unified\u0000biotokens, and present AtomFlow, a novel deep generative model under the\u0000flow-matching framework for the design of ligand-binding proteins from the 2D\u0000target molecular graph alone. Operating on representative atoms of biotokens,\u0000AtomFlow captures the flexibility of ligands and generates ligand conformations\u0000and protein backbone structures iteratively. We consider the multi-scale nature\u0000of biotokens and demonstrate that AtomFlow can be effectively trained on a\u0000subset of structures from the Protein Data Bank, by matching flow vector field\u0000using an SE(3) equivariant structure prediction network. Experimental results\u0000show that our method can generate high fidelity ligand-binding proteins and\u0000achieve performance comparable to the state-of-the-art model RFDiffusionAA,\u0000while not requiring bound ligand structures. As a general framework, AtomFlow\u0000holds the potential to be applied to various biomolecule generation tasks in\u0000the future.","PeriodicalId":501022,"journal":{"name":"arXiv - QuanBio - Biomolecules","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maximum DNA breakage efficacy is\u0000achieved when decays occur near DNA. Studies of double-strand breaks (DSBs)\u0000yields in plasmids revealed cutoff distances from DNA axis of 10.5-12 {AA},\u0000beyond which the mechanism of DSBs moves from direct to indirect effects, and\u0000the yield decreases rapidly. Some authors suggested that the average energy\u0000deposited in a DNA cylinder could explain such cutoffs. We aimed to study this\u0000hypothesis in further detail.Materials and methods: Using the Monte Carlo code\u0000CELLDOSE, we investigated the influence of the 125I atom position on energy\u0000deposits and absorbed doses per decay not only in a DNA cylinder, but also in\u0000individual strands, each modeled as 10 spheres encompassing the fragility sites\u0000for phosphodiester bond cleavage.Results: The dose per decay decreased much\u0000more rapidly for a sphere in the proximal strand than for the DNA cylinder. For\u0000example, when moving the 125I source from 10.5 {AA} to 11.5 {AA}, the average\u0000dose to the sphere dropped by 43%, compared to only 13% in the case of the\u0000cylinder.Conclusions: Explaining variations in DSBs yields with 125I position\u0000should consider the probability of inducing damage in the proximal strand\u0000(nearest to the 125I atom). The energy received by fragility sites in this\u0000strand is highly influenced by the isotropic (4$pi$) emission of 125I\u0000low-energy Auger electrons. The positioning of Auger emitters for targeted\u0000radionuclide therapy can be envisioned accordingly.","PeriodicalId":501022,"journal":{"name":"arXiv - QuanBio - Biomolecules","volume":"175 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite\u0000their utility, MD simulations are expensive, owing to the high dimensionality\u0000of molecular systems. Interactive molecular dynamics in virtual reality\u0000(iMD-VR) has recently been developed as a 'human-in-the-loop' strategy, which\u0000leverages high-performance computing to accelerate the researcher's ability to\u0000solve the hyperdimensional sampling problem. By providing an immersive 3D\u0000environment that enables visualization and manipulation of real-time molecular\u0000motion, iMD-VR enables researchers and students to efficiently and intuitively\u0000explore and navigate these complex, high-dimensional systems. iMD-VR platforms\u0000offer a unique opportunity to quickly generate rich datasets that capture human\u0000experts' spatial insight regarding molecular structure and function.
