Limits: Google Scholar search engine, articles and patents, title, full amino acid name, since 2010 to 05/28/12. Notes: * Sum of Glutamate: 3,670 + “Glutamic Acid”: 618 = 4,288; ** Sum of Cysteine: 2,390 + Cystine: 243 = 2,633; *** Sum of Aspartate: 918 + “Aspartic Acid”: 288 = 1,206; # Sum of “Stop Codons”: 18 + “Stop Codon”: 52 + “Nonsense Codons”: 4 + “Nonsense Codon”: 2 = 76; for comparison with the normal Stops, “Nonsense Mutation”: 135 + “Nonsense Mutations”: 54 + “Stop Mutation”: 10 = 199, locating these mutations with 15 hits above N  [05/28/2012].
