Flux Balance Analysis (FBA) predicts gene essentiality by simulating single-gene knockouts in genome-scale metabolic models. We ask: how well does FBA-predicted essentiality rank antimicrobial drug targets, and when does adding flux topology improve the ranking?

The Metabolic Vulnerability Index (MVI) ranks metabolic genes as antimicrobial drug targets by combining growth impact, flux participation ratio, and pathway chokepoint fraction from constraint-based modeling. We validate MVI on E.
