coli pathways overlaid with predicted reaction flux data. Metabolites that are shared between pathways are indicated by drawing connecting lines between them.įigure 2 shows a collage consisting of two E. This diagram has already been manually adjusted by repositioning the pathways relative to each other and tweaking node font sizes and shapes. coli pathways overlaid with gene expression data. Figure 1 depicts a Pathway Collage consisting of four E. Three example Pathway Collage figures are illustrated here. Feel free to experiment yourself with the example pathway collage online at, or create your own following the instructions below. This application, implemented using the Cytoscape.js open-source JavaScript graph visualization library, supports panning, zooming, and all the editing and customization operations described in this post and the documentation embedded within the Pathway Collage Viewer itself. Pathway Collages can be explored and edited via the Pathway Collage Viewer web browser application. Pathway Collages, new in Pathway Tools version 19.5, are an attempt to bridge this gap, allowing users to create high-quality, customized, user-manipulable diagrams containing collections of user-specified pathways. However, to understand some biochemical situations, viewing a single pathway is insufficient, whereas viewing the entire metabolic network results in information overload. When a more global view is called for, our cellular overview diagram depicts the entire metabolic network for an organism, with capabilities for selective highlighting and overlay of omics data. fumigatus’s metabolism to reveal dapsone, sulfamethazine, lovastatin and 3-bromopyruvic acid as potential drugs for the treatment of Aspergillosis.Pathway Tools has long been recognized for the quality of our automatically generated individual metabolic pathway diagrams, which are intuitive to biologists, can be shown at varying levels of detail, and can be customized in various ways, including with the overlay of omics data. Our study provides a deeper insight into the mechanisms of A. Based on docking scores and MM-GBSA results, molecular simulations were carried out for 1AJ2-dapsone, 1DIS-sulfamethazine, 1T02-lovastatin and 70YL-3-bromopyruvic acid complexes, which validated our findings. Further, molecular docking and MM-GBSA analysis were performed with ligands chosen from DrugBank, and PubChem, and validated by experimental evidence and existing literature based on results from kinetic modeling and PPI network analysis. Based on the findings, dihydropteroate-synthase, dihydrofolate-reductase, 4-amino-4-deoxychorismate synthase, HMG-CoA-reductase, PG-isomerase and hexokinase could act as potential drug targets. For further analysis of the interaction of drug targets identified, a protein–protein interaction (PPI) network was built, and hub nodes were identified using the Cytohubba package from Cytoscape. While focusing on the folate biosynthesis, ergosterol biosynthesis and glycolytic pathway sensitivity, time-course and steady-state analysis were performed to find the proteins/enzymes that are essential in the pathway and can be considered as potential drug targets. Our work focused on developing kinetic models of critical pathways crucial for the survival of A. To understand the pathogenicity of any organism, it is critical to identify the significant metabolic pathways that are involved. The diagnosis and treatment are difficult due to the diversity of individuals and risk factors and still pose a challenge for medical professionals. Aspergillosis is a major causative factor for morbidity in those with impaired immune systems, often caused by Aspergillus fumigatus.
