B55 MTB000052
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
704187–704247 (+ strand), 61 nt, on H37Rv
(NC_000962.3).
Intergenic (no overlapping coding sequence).
Upstream neighbour Rv0609A
(130 bp).
Downstream neighbour Rv0610c
(505 bp).
Intra-MTBC variation
| Genomes surveyed | 145,209 |
| Variable sites | 61 |
| Variants reaching 0.1 % of genomes | 2 |
| Carriers of the most widespread variant | 169 |
Coverage control
Variant density inside this RNA: 100.0 sites/100 bp, versus 77.1 in the flanking ±500 bp (GC 70.5 %). 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
75.4 % of bases are paired in the minimum-free-energy fold (46 paired, 15 unpaired). Folded in isolation; the in vivo structure may differ (partners, co-transcriptional folding).
Legacy record
B55, putative small regulatory RNA (See Arnvig and Young, 2009). This region is a possible MT-complex-specific genomic island (See Becq et al., 2007).
