Fig. 3: The TMcin family is broadly distributed throughout Gram-positive bacteria.

a Unrooted phylogenetic tree of TmcA (pre-TMcin protein). Node support is indicated by shaded diamonds. The most abundant bacterial phylum, family, and genus taxonomic groups are marked with colored boxes to the right of TmcA taxa. b Representative operon structures of TMcin BGCs (example accession number, BGC locus).
