N denotes any of A, U, G, and C, and R denotes A and G. The values in the initiation codons indicate the number of known initiation codons. The codon reassignments of each deviant code are arranged from top to bottom in the estimated order of reassignments. Compiled from http://www3.ncbi.nlm.nih.gov/htbin-post/Taxonomy/wprintgc?mode=c.
