Rv3681c whiB4 WhiB-type transcription regulator CDS 4121198 4121554 - 357 118 TRUE

Rv3681c (WhiB-type transcription regulator) is predicted to be co-regulated in modules bicluster_0400 with residual 0.51 and bicluster_0421 with residual 0.58.

This regulation is possibly mediated by two de-novo identified cis-regulatory motifs in each module with e-values , 0.01 and 0.12 for bicluster_0400 and 360.00 and 130.00 for bicluster_0421 respectively.

These modules are enriched for following go terms: carboxypeptidase activity, thiosulfate sulfurtransferase activity, unfolded protein binding, exopeptidase activity .

This gene is found to be for growth on cholesterol.

cell wall

cell wall

The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan.

Quantitative Proteomics Data

t-test p-value Cholesterol/Glycerol Ratio
0.610000 1.94

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.
