MTS2975 MTB000080

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

4317073–4317165 (+ strand), 93 nt, on H37Rv (NC_000962.3). Intergenic (no overlapping coding sequence). Upstream neighbour Rv3843c (477 bp). Downstream neighbour Rv3844 (1610 bp).

Coverage control

Variant density inside this RNA: 102.2 sites/100 bp, versus 88.7 in the flanking ±500 bp (GC 57.0 %). 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

71.0 % of bases are paired in the minimum-free-energy fold (66 paired, 27 unpaired). Folded in isolation; the in vivo structure may differ (partners, co-transcriptional folding).

Legacy record

MTS2975, putative small regulatory RNA (See Arnvig et al., 2011), ends not mapped, ~100 bp band detected by Northern blot.
