Comments Duplicates in Bacillus subtilis or Bacillus amyloliquefaciens are due to the presence of a phage-derived TS. See: PubMed=9648749. Tam N.H., Borriss R.; "Genes encoding thymidylate synthases A and B in the genus Bacillus are members of two distinct families."; Mol. Gen. Genet. 258:427-430(1998). Archaeal thyA belong to a separate family (MF_01686)
