30S ribosomal protein S12 methylthiotransferase accessory factor YcaO
YcaO acts as a partner for RimO to achieve the modification of ribosomal protein S12. Homologs of YcaO are involved a wide variety of RiPP (ribosomally translated, post-translationally modified peptide) natural product biosynthesis pathways. Some members of this family have an additional N-terminal OsmC-like domain.
