BION web server: predicting non-specifically bound surface ions

Marharyta Petukh, Taylor Kimmet, Emil Alexov
2013 Computer applications in the biosciences : CABIOS  
Results: Here, we report a web server, the BION web server, which addresses the demand for tools of predicting surface bound ions, for which specific interactions are not crucial; thus, they are difficult  ...  The coordinate file with predicted bound ions is displayed on the output and is available for download.  ...  This method is implemented into a web server, the BION web server, which allows predicting non-specific bound ions on the surface of proteins.  ...

BION-2: Predicting Positions of Non-Specifically Bound Ions on Protein Surface by a Gaussian-Based Treatment of Electrostatics

H. B. Mihiri Shashikala, Arghya Chakravorty, Shailesh Kumar Panday, Emil Alexov
2020 International Journal of Molecular Sciences  
Here, we report a new release of a computational method, the BION-2 method, that predicts the positions of non-specifically surface-bound ions.  ...  Although the role of specifically bound ions ranges from actively providing structural compactness via coordination of charge–charge interactions to numerous enzymatic activities, non-specifically surface-bound  ...  In this work, we report a new development of BION [21, 22] , the BION-2, which is a method and a web server to predict non-specifically surface-bound ions.  ...

Ion binding to biological macromolecules

Marharyta Petukh, Emil Alexov
2014 Asian journal of physics : an international quarterly research journal  
It is indicated that specifically bound ions are relatively easier to be revealed while non-specifically associated ions are difficult to predict.  ...  In addition, the binding and the residential time of non-specifically bound ions are very much sensitive to the environmental factors in the cells, specifically to the local pH and ion concentration.  ...  BION web server-Usually the positions of nonspecific bound ions are on the surface of proteins.  ...

On the electrostatic properties of homodimeric proteins

Brandon Campbell, Marharyta Petukh, Emil Alexov, Chuan Li
2014 Journal of Theoretical and Computational Chemistry  
In addition, the surface points with highest potential are located in the proximity of the interfacial plane of the homodimeric complexes.  ...  These findings indicate that frequently homodimerization provides specific electrostatic features needed for the function of proteins.  ...  The predictions are based on the magnitude of the electrostatic potential at selected surface-bound grid points and biophysical properties of ions such as radius and charge.  ...

2020 Frontiers in Microbiology  
In silico protein-protein interaction predictions indicated that EV proteins could interact with host proteins, including the immunomodulatory transcription factor NF-κB.  ...  Indeed, EVs displayed an anti-inflammatory effect by modulating the NF-κB pathway; this was dependent on their concentration and on the proinflammatory inducer (LPS-specific).  ...  For the first method of prediction, EVs and human proteins were submitted to the InterSPPI web server (Lian et al., 2019) , a machine-learning-based predictor.  ...
