常用核酸和氨基酸代码

Amino Acids Table

Here is a list of the standard one-letter amino acid codes and their three-letter equivalents. The synonymous codons and their depiction in the IUB codes are shown. You should recognize that the codons following semicolons ( are not sufficiently specific to define a single amino acid even though they represent the best possible backtranslation into the IUB codes!Symbol 3-letter Code Amino-acid Codons A Ala Alanine GCT,GCC,GCA,GCG B Asp,Asn Aspartic, Asparagine GAT,GAC,AAT,AAC C Cys Cysteine TGT,TGC D Asp Aspartic GAT,GAC E Glu Glutamic GAA,GAG F Phe Phenylalanine TTT,TTC G Gly Glycine GGT,GGC,GGA,GGG H His Histidine CAT,CAC I Ile Isoleucine ATT,ATC,ATA K Lys Lysine AAA,AAG L Leu Leucine TTG,TTA,CTT,CTC,CTA,CTG M Met Methionine ATG N Asn Asparagine AAT,AAC P Pro Proline CCT,CCC,CCA,CCG Q Gln Glutamine CAA,CAG R Arg Arginine CGT,CGC,CGA,CGG,AGA,AGG S Ser Serine TCT,TCC,TCA,TCG,AGT,AGC T Thr Threonine ACT,ACC,ACA,ACG V Val Valine GTT,GTC,GTA,GTG W Trp Tryptophan TGG X Xxx Unknown Y Tyr Tyrosine TAT,TAC Z Glu,Gln Glutamic, Glutamine GAA,GAG,CAA,CAG * End Terminator TAA,TAG,TGA Standard Genetic Code U C A G U UUU Phe F UUC Phe F UUA Leu L UUG Leu L UCU Ser S UCC Ser S UCA Ser S UCG Ser S UAU Tyr Y UAC Tyr Y UAA Stop UAG Stop UGU Cys C UGC Cys C UGA Stop UGG Trp W C CUU Leu L CUC Leu L CUA Leu L CUG Leu L CCU Pro P CCC Pro P CCA Pro P CCG Pro P CAU His H CAC His H CAA Gln Q CAG Gln Q CGU Arg R CGC Arg R CGA Arg R CGG Arg R A AUU Ile I AUC Ile I AUA Ile I AUG Met M ACU Thr T ACC Thr T ACA Thr T ACG Thr T AAU Asn N AAC Asn N AAA Lys K AAG Lys K AGU Ser S AGC Ser S AGA Arg R AGG Arg R G GUU Val V GUC Val V GUA Val V GUG Val V GCU ALA A GCC ALA A GCA ALA A GCG ALA A GAU Asp D GAC Asp D GAA Glu E GAG Glu E GGU Gly G GGC Gly G GGA Gly G GGG Gly G
