thraustochytrium mitochondrial code thraustochytrium mitochondrial code the thraustochytrium mitochondrial code (translation table 23) is a genetic code found in the mitochondria of the labyrinthulid protist thraustochytrium aureum. the mitochondrial genome was sequenced by the organelle genome megasequencing program. code aas = ff*lssssyy**cc*wllllpppphhqqrrrriiimttttnnkkssrrvvvvaaaaddeegggg starts = --------------------------------m--m---------------m------------ base1 = ttttttttttttttttccccccccccccccccaaaaaaaaaaaaaaaagggggggggggggggg base2 = ttttccccaaaaggggttttccccaaaaggggttttccccaaaaggggttttccccaaaagggg base3 = tcagtcagtcagtcagtcagtcagtcagtcagtcagtcagtcagtcagtcagtcagtcagtcag bases: adenine (a), cytosine (c), guanine (g) and thymine (t) or uracil (u). amino acids: alanine (ala, a), arginine (arg, r), asparagine (asn, n), aspartic acid (asp, d), cysteine (cys, c), glutamic acid (glu, e), glutamine (gln, q), glycine (gly, g), histidine (his, h), isoleucine (ile, i), leucine (leu, l), lysine (lys, k), methionine (met, m), phenylalanine (phe, f), proline (pro, p), serine (ser, s), threonine (thr, t), tryptophan (trp, w), tyrosine (tyr, y), valine (val, v) differences from the standard code it is the similar to the bacterial code (translation table 11) but it contains an additional stop codon (tta) and also has a different set of start codons. dna codonsrna codonsthis code (23)standard code (1) ttauuastop = ter (*)leu (l) systematic range and comments mitochondria of thraustochytrium aureum.
