Annotation: from legacy to revised
| Legacy (H37Rv / Mycobrowser) | hypothetical protein |
| MTBC0 PGAP re-annotation | DUF5073 family protein |
| Revised (this work) | DUF5073 family protein. |
Auto-curated: this verdict and function were generated by rules from
PGAP + Pfam + Foldseek and have not been hand-reviewed.

Orthology-based transfer (eggNOG 5.0.2, diamond). EC/KO/GO/CAZy are
computed annotations, not manual curation; cross-check against the primary literature
before treating a specific reaction as established.
Conservation & selection (intra-MTBC, 145 209 strains)

pN/pS from segregating SNPs (singletons removed) normalised by possible sites.
Low pN/pS = purifying selection (a strong signal that a "hypothetical" is a real, constrained gene).
A high pN/pS is ambiguous: relaxed constraint or positive selection (drug resistance, antigenic
variation) inflate it; e.g. rpoB/katG/pncA score high here for resistance, not loss of function. A
clonal disruption (one allele over a clade) suggests lineage pseudogenisation; a
convergent one (many independent alleles) is typical of resistance loss-of-function.

STRING combines evidence channels (neighborhood, fusion, cooccurrence, coexpression,
experimental, database, text-mining) into a 0–1000 score. The ctx
badge marks edges carried by the genomic-context channels (conserved neighborhood, fusion,
phylogenetic co-occurrence), which are independent of orthology and structure and the strongest signal for an
unknown gene. The no text-mining column recomputes the score from data alone, so a link that does not
depend on the literature is visible. Association is a function hypothesis, not proof: corroborate with
the operon context and the primary literature before assigning a function.
