ncRv12023 MTB000143

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

2268164–2268231 (+ strand), 68 nt, on H37Rv (NC_000962.3). Intergenic (no overlapping coding sequence). Upstream neighbour Rv2023c (56 bp). Downstream neighbour Rv2024c (462 bp).

Coverage control

Variant density inside this RNA: 91.2 sites/100 bp, versus 73.2 in the flanking ±500 bp (GC 58.8 %). 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

70.6 % of bases are paired in the minimum-free-energy fold (48 paired, 20 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)
