Class RNAToAminoAcidTranslator

java.lang.Object

org.biojava.nbio.core.sequence.template.AbstractCompoundTranslator<NucleotideCompound,AminoAcidCompound>

org.biojava.nbio.core.sequence.transcription.RNAToAminoAcidTranslator

All Implemented Interfaces:

CompoundTranslator<NucleotideCompound,AminoAcidCompound>

public class RNAToAminoAcidTranslator
extends AbstractCompoundTranslator<NucleotideCompound,AminoAcidCompound>

Takes a Sequence of NucleotideCompound which should represent an RNA sequence (RNASequence is good for this) and returns a list of Sequence which hold AminoAcidCompound. The translator can also trim stop codons as well as changing any valid start codon to an initiating met.

Method Detail

createSequences

public List<Sequence<AminoAcidCompound>> createSequences(Sequence<NucleotideCompound> originalSequence)

Performs the core conversion of RNA to Peptide. It does this by walking a windowed version of the given sequence. Any trailing DNA base pairs are ignored according to the specification of WindowedSequence.

Specified by:

createSequences in interface CompoundTranslator<NucleotideCompound,AminoAcidCompound>

Overrides:

createSequences in class AbstractCompoundTranslator<NucleotideCompound,AminoAcidCompound>

postProcessCompoundLists

protected void postProcessCompoundLists(List<List<AminoAcidCompound>> compoundLists)

Performs the trimming of stop codons and the conversion of a valid start amino acid to M

Specified by:

postProcessCompoundLists in class AbstractCompoundTranslator<NucleotideCompound,AminoAcidCompound>

trimStop

protected void trimStop(List<AminoAcidCompound> sequence)

Imperfect code. Checks the last amino acid to see if a codon could have translated a stop for it. Left in for the moment

translateNCodons

public boolean translateNCodons()

Indicates if we want to force exact translation of compounds or not i.e. those with internal N RNA bases. This will cause a translation to an X amino acid
