The Anaerococcus and Onthovivens genetic code (tentative code number 36) translates CGG to
tryptophan
Tryptophan (symbol Trp or W)
is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromat ...
, as determined by the codon assignment software Codetta;
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
The Clostridia are a highly polyphyletic class of Bacillota, including '' Clostridium'' and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them ...

Onthovivens'' in the class ''
Bacilli
Bacilli is a Taxonomy (biology), taxonomic Class (biology), class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as ''Bacillus anthracis'' (the cause of anthrax). ''Bacilli'' ...

List of genetic codes
While there is much commonality, different parts of the tree of life use slightly different genetic codes. When translating from genome to protein, the use of the correct genetic code is essential. The mitochondrial codes are the relatively well ...
