G2 MTB000054

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

1914962–1915190 (- strand), 229 nt, on H37Rv (NC_000962.3). Intergenic (no overlapping coding sequence). Upstream neighbour Rv1689 (86 bp). Downstream neighbour Rv1690 (337 bp).

Coverage control

Variant density inside this RNA: 67.2 sites/100 bp, versus 60.5 in the flanking ±500 bp (GC 62.0 %). 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

64.6 % of bases are paired in the minimum-free-energy fold (148 paired, 81 unpaired). Folded in isolation; the in vivo structure may differ (partners, co-transcriptional folding).

Legacy record

G2, putative small regulatory RNA (See Arnvig and Young, 2009). Alternate 5'-end at position 1915028. Alternate 3'-end at position 1914977.
