Ive iterations search for new reactions that have all required substrates marked as accessible until no new reaction can be added. Each metabolite j have a synthetic accessibility value Sj representing the number of iterations before this metabolite became accessible and the Synthetic Accessibility of the network as a whole, Snet, is the sum of Sj of each of the output metabolites. Increases in Snet resulting from gene deletions are predicted as being deleterious. Synthetic accessibility is a simpler method than FBA and gives comparable results on the prediction of essential genes demonstrating that the topology of the network is the principal factor influencing essentiality. We use our own implementation of the algorithm.Local structure similarityCompeting interests The authors To be an increase in errors of commission (i.e., failures declare that they have no competing interests.The identification of local structure similarities is separated into three steps: the creation of a three dimensionalAuthors' contributions ML and TC created the reconstructed metabolic network and performed the single and double mutant experiments.
