Annotation: from legacy to revised

Legacy (H37Rv / Mycobrowser)cell division protein RodA
MTBC0 PGAP re-annotationcell shape-determining peptidoglycan glycosyltransferase RodA
Revised (this work)Cell shape-determining peptidoglycan glycosyltransferase RodA. Pfam: FTSW_RODA_SPOVE (PF01098.25).

Auto-curated: this verdict and function were generated by rules from PGAP + Pfam + Foldseek and have not been hand-reviewed.

Curated reference (UniProt)

UniProt P9WN99 SwissProt · reviewed · Evidence at protein level
UniProt namePeptidoglycan glycosyltransferase RodA
EC (curated) EC 2.4.99.28
Curated functionTransglycosylase involved in peptidoglycan cell wall formation. Required for the regulation of cell length. Plays critical roles for the survival of the pathogen inside the host. Required for both bacterial survival and formation of granuloma structures in a guinea pig infection model.

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 0.377 · purifying
Polymorphic sites (≥ 0.1% of strains) 4 synonymous, 4 missense, 0 nonsense, 0 frameshift

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.
