mcr3 MTB000064

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

1471619–1471742 (+ strand), 124 nt, on H37Rv (NC_000962.3). Intergenic (no overlapping coding sequence). Upstream neighbour Rv1315 (42 bp). Downstream neighbour Rv1316c (5392 bp).

Coverage control

Variant density inside this RNA: 91.9 sites/100 bp, versus 57.6 in the flanking ±500 bp (GC 46.0 %). 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

61.3 % of bases are paired in the minimum-free-energy fold (76 paired, 48 unpaired). Folded in isolation; the in vivo structure may differ (partners, co-transcriptional folding).

Legacy record

mcr3, putative small regulatory RNA (See DiChiara et al., 2010). 5'-end mapped by 5'RLM-RACE in M. bovis BGC Pasteur, 3'-end not mapped.
