Summary

Symbol Product Feature Type Start End Strand Length AA Length is TF
Rv2839c infB Translation initiation factor 2 CDS 3145171 3147873 - 2 703 900 FALSE

Rv2839c (Translation initiation factor 2) is predicted to be co-regulated in modules bicluster_0428 with residual 0.47 and bicluster_0528 with residual 0.42.

This regulation is possibly mediated by two de-novo identified cis-regulatory motifs in each module with e-values , 0.00 and 0.52 for bicluster_0428 and 0.00 and 47.00 for bicluster_0528 respectively.

These modules are enriched for following go terms: ATPase activity, coupled, ATP-dependent DNA helicase activity, ATPase activity, nuclease activity .

This gene is found to be for growth on cholesterol.

translational initiation

translational initiation

Details: 
The process preceding formation of the peptide bond between the first two amino acids of a protein. This includes the formation of a complex of the ribosome, mRNA, and an initiation complex that contains the first aminoacyl-tRNA.

translation

translation

Details: 
The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA. Translation ends with the release of a polypeptide chain from the ribosome.

extracellular region

extracellular region

Details: 
The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

cell wall

cell wall

Details: 
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
NA NA

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.
