Organisms that use more than the 20+2 commonly occurring amino acids?
At this point in time it appears that no known organisms use amino acids beyond the standard repertoire of the 20+2 common amino acids (the +2 being selanocysteine and pyrrolysine) to construct proteins directly from the ribosome. The extensive review provided by Ann Rev Genetics 2017 mentions only selanocysteine and pyrrolysine, and no other amino acids beyond that.
