Rv2710 sigB RNA polymerase sigma factor SigB CDS 3022461 3023432 + 972 323 FALSE

Rv2710 (RNA polymerase sigma factor SigB) is predicted to be co-regulated in modules bicluster_0073 with residual 0.60 and bicluster_0335 with residual 0.58.

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_0073 and 57.00 and 1,600.00 for bicluster_0335 respectively.

These modules are enriched for following go terms: .

This gene is found to be for growth on cholesterol.

sigma factor activity

sigma factor activity

Details: 
A sigma factor is the promoter specificity subunit of eubacterial-type multisubunit RNA polymerases, those whose core subunit composition is often described as alpha(2)-beta-beta-prime. (This type of multisubunit RNA polymerase complex is known to be found in eubacteria and plant plastids). Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, this binds specifically to promoter sequences, with the sigma factor making sequence specific contacts with the promoter elements. The sigma subunit is released from the elongating form of the polymerase and is thus free to act catalytically for multiple RNA polymerase core enzymes.

DNA-dependent transcription, initiation

DNA-dependent transcription, initiation

Details: 
Any process involved in the assembly of the RNA polymerase preinitiation complex (PIC) at the core promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. The initiation phase ends just before and does not include promoter clearance, or release, which is the transition between the initiation and elongation phases of transcription.

response to hypoxia

response to hypoxia

Details: 
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.

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.
