ncRv3520 MTB000157
ncRNA Putative small regulatory RNA
This is an RNA, not a coding gene: it belongs to a separate track and carries none of the protein evidence layers.
Location
3956291–3956550 (+ strand), 260 nt, on H37Rv
(NC_000962.3).
Overlaps: Rv3520c.
Upstream neighbour Rv3519
(31 bp).
Downstream neighbour Rv3521
(971 bp).
Intra-MTBC variation
| Genomes surveyed | 145,209 |
| Variable sites | 187 |
| Variants reaching 0.1 % of genomes | 3 |
| Carriers of the most widespread variant | 897 |
Coverage control
Variant density inside this RNA: 71.9 sites/100 bp, versus 72.6 in the flanking ±500 bp (GC 64.6 %). The flanks act as an internal witness: if variants are called normally around the RNA but none becomes widespread inside it, the constraint is real rather than a sequencing gap.
Verdict: n/a (a des variants communs)
Predicted secondary structure
72.3 % of bases are paired in the minimum-free-energy fold (188 paired, 72 unpaired). Folded in isolation; the in vivo structure may differ (partners, co-transcriptional folding).
Legacy record
Supported by sRNA-Seq in H37Rv (see DeJesus et al. 2017)
