AS1726 MTB000055

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

1952291–1952503 (- strand), 213 nt, on H37Rv (NC_000962.3). Overlaps: Rv1726. Upstream neighbour Rv1725c (540 bp). Downstream neighbour Rv1727 (767 bp).

Coverage control

Variant density inside this RNA: 66.7 sites/100 bp, versus 73.8 in the flanking ±500 bp (GC 66.7 %). 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

62.0 % of bases are paired in the minimum-free-energy fold (132 paired, 81 unpaired). Folded in isolation; the in vivo structure may differ (partners, co-transcriptional folding).

Legacy record

AS1726, putative small regulatory RNA (See Arnvig and Young, 2009). Alternate 5'-ends at positions 1952400, 1952375, 1952367, and 1952351.
