  1. Shown is a comparison of transposon site hybridization (TraSH) and genome-scale metabolic network of M. tuberculosis (GSMN-TB) predictions of gene essentiality with experimentally determined phenotype for genes that have been investigated by specific gene knockout. E, essential; NE, nonessential.
