The Anaerococcus and Onthovivens genetic code (tentative code number 36) translates CGG to tryptophan, as determined by the codon assignment software Codetta; [1] it was further shown that this recoding is associated with a special tRNA with the appropriate anticodon and tRNA identity elements appropriate for such decoding. As currently known, this code is limited to two distinct clades, the genus Anaerococcus in the class Clostridia and the genus Onthovivens in the class Bacilli , as defined by the GTDB taxonomy system [2] release 220. Codetta originally called the Anaerococcus and Onthovivens code for the following genome assemblies: GCA_000024105.1, GCA_900445285.1, GCA_902500265.1, GCA_900258475.1, GCA_002399785.1, GCA_004558005.1, GCA_900540365.1, GCA_900540395.1, GCA_900545015.1.
