In HVoltBb/kondonz: A Comprehensive Codon Analysis Toolbox

Description Usage Arguments Details Value References Examples

This function translate an array of codons into the corresponding amino acid sequence using the codon table of choice.

1	dna2aa(x, aaNoLetters = 3, y = 0)

`x`	a KZsqns object of codons or a list of such objects
`aaNoLetters`	a number to assign the format of animo acid. 1 = one-letter abbreviation, 3 = three-letter abbreviation. If it defaults into the 3-letter abbreviation when no number or a different number is specified
`y`	a number to assign the type of codon table to be used for the translation. 0 = standard codon table, 2 = vertibrate mitchodrial, 3 = yeast mitochondrial, 4 = mold, protozoan, and Coelenterate mitochondrial and Mycoplasma/Spiroplasma, 5 = invertebrate mitochondrial, 6 = Ciliate, Dasycladacean and Hexamita nuclear, 9 = Echinoderm and flatworm mitochondrial, 10 = Euplotid nuclear, 11 = bacterial, Archaeal and plant plastid, 12 = alternative yeast nuclear, 13 = Ascidian mitochondrial, 14 = alternative flatworm mitochondrial, 16 = Chlorophycean mitochondrial, 21 = Trematode mitochondrial, 22 = Scenedesmus obliquus mitochondrial, 23 = Thraustochytrium mitochondrial, 24 = Pterobranchia mitochondrial, 25 = candidate division SR1 and Gracilibacteria, 26 = Pachysolen tannophilus nuclear, 29 = Mesodinium nuclear, 30 = Peritrich nuclear. If no number is specified or an option other than those provided above is specified, there will be a warning and the standard codon table will be used

Codon tables were based on the list compiled by Andrzej Elzanowski and Jim Ostell [1] at NCBI, Bethesda, Maryland, USA. The numbering of codon tables respects the order in Elzanowski and Ostell [1] (except the standard code, which was numbered 0 in this package). There are three addditional codon tables listed in Elzanowski and Ostell [1] (27 Karyorelict nuclear, 28 Condylostoma nuclear and 31 Blastocrithidia nuclear), but were excluded in this package, because these codon tables include codons that can be either intepreted as a AA coding codon or stop codon, and the AA sequence can not be determined based on the DNA sequence alone. The codon table data were available as "CodonTable#", where "#" denote the numeric order of the codon table. For example, "CodonTable21" is the Trematode mitochonrial code table.

a character array of animo-acids, or a list of such arrays when x is a list
