Rv1981c (Ribonucleotide reductase of class Ib (aerobic), beta subunit (EC is predicted to be co-regulated in modules bicluster_0309 with residual 0.40 and bicluster_0519 with residual 0.54.

This regulation is possibly mediated by two de-novo identified cis-regulatory motifs in each module with e-values , 1,400.00 and 2,000.00 for bicluster_0309 and 1,600.00 and 7,500.00 for bicluster_0519 respectively.

These modules are enriched for following go terms: organonitrogen compound metabolic proces..., carboxylic acid biosynthetic process, organic acid biosynthetic process, small molecule metabolic process.

This gene is found to be for growth on cholesterol.

ribonucleoside-diphosphate reductase activity, thioredoxin disulfide as acceptor

ribonucleoside-diphosphate reductase activity, thioredoxin disulfide as acceptor

Catalysis of the reaction: 2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin. Thioredoxin disulfide is the oxidized form of thioredoxin.

Quantitative Proteomics Data

t-test p-value Cholesterol/Glycerol Ratio
0.030000 1.07

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.
