Rv2957 PGL/p-HBAD biosynthesis glycosyltransferase CDS 3309470 3310297 + 828 275 FALSE

Rv2957 (PGL/p-HBAD biosynthesis glycosyltransferase) is predicted to be co-regulated in modules bicluster_0162 with residual 0.54 and bicluster_0282 with residual 0.48.

This regulation is possibly mediated by two de-novo identified cis-regulatory motifs in each module with e-values , 45.00 and 5,400.00 for bicluster_0162 and 0.14 and 0.27 for bicluster_0282 respectively.

These modules are enriched for following go terms: cysteine biosynthetic process from serin..., cysteine biosynthetic process, cysteine metabolic process, L-serine metabolic process .

This gene is found to be for growth on cholesterol.

glycolipid biosynthetic process

glycolipid biosynthetic process

The chemical reactions and pathways resulting in the formation of glycolipid, a class of 1,2-di-O-acylglycerols joined at oxygen 3 by a glycosidic linkage to a carbohydrate part (usually a mono-, di- or tri-saccharide).

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.
