Candidate division SR1 and gracilibacteria code

 The candidate division SR1 and gracilibacteria code (translation table 25) is used in two groups of (so far) uncultivated bacteria found in marine and fresh-water environments and in the intestines and oral cavities of mammals among others.[1] The difference to the standard and the bacterial code is that UGA represents an additional glycine codon and does not code for termination.[2]
