Orienting biochemical reactions in metabolic pathways and networks

Abstract

Aquest estudi ofereix una exploració integral sobre l'orientació d'hipergràfs dins de les vies metabòliques. El nostre focus va estar en la formulació d'un model AMPL, permetent als investigadors obtenir solucions efectives mitjançant l'optimització de ILP. Les principals contribucions del nostre treball inclouen: - Desenvolupament d'un model lògicament robust per resoldre el problema de l'orientació d'hiperarestes en vies metabòliques. - Avaluació comparativa del model respecte alternatives, identificant punts forts, punts febles i escenaris d'aplicació òptims. - Introducció de restriccions addicionals considerades significatives en el camp de les vies metabòliques, incloentí: - La prevenció de la inversió en reaccions específiques. - La identificació de certs vèrtexs com interns. - La identificació de certs vèrtexs com externs. A més, aquest article presenta una eina d'interfície gràfica d'usuari (GUI) amigable que facilita l'exploració del model, l'anàlisi de resultats, l'addició de restriccions i l'orientació de vies metabòliques en escenaris del món real.

This study offers a comprehensive exploration into the orientation of hypergraphs within metabolistic pathways. Our focus was on formulating an AMPL model, enabling researchers to attain effective solutions through ILP optimization. Key contributions of our work encompass: - Development of a logically robust model for solving hyperedge orientation in metabolistic pathways. - Benchmarking the model against alternatives, identifying strengths, weaknesses, and optimal application scenarios. - Introduction of additional constraints deemed significant in metabolistic pathways, including: - Prevention of inversion in specific reactions. - Identification of certain vertices as internal. - Identification of certain vertices as external. Additionally, this paper introduces a user-friendly GUI tool that facilitates model exploration, result analysis, constraint addition, and pathway orientation in real-world scenarios.
