TrpR homologue YerC/YecD (IPR013368)

Short name: YecD_YerC

Overlapping homologous superfamilies

Family relationships


These proteins are found mostly in the Firmicutes (Bacillus and other related Gram-positive bacteria). They are similar in sequence to the trp operon repressor TrpR IPR013335, but represent a distinct clade. At least one species, Xylella fastidiosa, in the Proteobacteria, has a member of both this family and IPR013335. Several genomes with a member of this family do not synthesize tryptophan, and members of this family should not be considered trp operon repressors without new evidence.
