ncRv1821 MTB000141
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
2068863–2068962 (+ strand), 100 nt, on H37Rv
(NC_000962.3).
Overlaps: Rv1821.
Upstream neighbour Rv1820
(2421 bp).
Downstream neighbour Rv1822
(118 bp).
Intra-MTBC variation
| Genomes surveyed | 145,209 |
| Variable sites | 59 |
| Variants reaching 0.1 % of genomes | 1 |
| Carriers of the most widespread variant | 942 |
Coverage control
Variant density inside this RNA: 59.0 sites/100 bp, versus 57.7 in the flanking ±500 bp (GC 64.0 %). 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
78.0 % of bases are paired in the minimum-free-energy fold (78 paired, 22 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)
