Rv1963c mce3R Transcriptional repressor Mce3R, TetR family CDS 2205582 2206802 - 1 221 406 TRUE

Rv1963c (Transcriptional repressor Mce3R, TetR family) is predicted to be co-regulated in modules bicluster_0434 with residual 0.58 and bicluster_0486 with residual 0.55.

This regulation is possibly mediated by two de-novo identified cis-regulatory motifs in each module with e-values , 0.00 and 0.00 for bicluster_0434 and 500.00 and 840.00 for bicluster_0486 respectively.

These modules are enriched for following go terms: cellular macromolecule catabolic process, cellular protein metabolic process, coenzyme biosynthetic process, cofactor biosynthetic process DNA binding, nucleic acid binding.

This gene is found to be for growth on cholesterol.

How essentiality calculations were done?

The relative representation of each mutant was determined by calculating the fold change (sequence reads/insertion in cholesterol divided by sequence reads/insertion in glycerol) for each gene. Statistical significance was determined by t-test. Each insertion site in each replicate sample was treated as a separate data point. The hyperbola used for defining genes specifically required for growth in cholesterol was defined by the formula, y = 3.8/x+0.7. Genes above this line are annotated as required for growth on cholesterol.

TRIP log2 fold abundance change

reports the log2 abundance fold change of each TFI strain, relative to no induction, in absence or presence of drug, averaged across experimental replicates. Also reported are the accompanying z-scores and two-sided t-test p-values for each TFI strain under each condition. Please refer to Ma et al., 2020, Nature Microbiology for more information.
