Constructor Detail

PointMutation

public PointMutation(int position,
                     String wtResidue,
                     String mutResidue)
              throws MutationException

Initialize the object and call the base class constructor.

Parameters:

position - the sequence position or start position of the mutation

wtResidue - the wild-type (pre-mutation) residue identity (a string)

mutResidue - the mutant (post-mutation) residue identity (a string)

Throws:

MutationException - Residues identities are validated to ensure that they are within the canonical set of amino acid residues are normalized to their one-letter abbreviations.

PointMutation

public PointMutation(String position,
                     String wtResidue,
                     String mutResidue)
              throws MutationException

Throws:

MutationException

Method Detail

normalizeResidueIdentity

public char normalizeResidueIdentity(String residue)
                              throws MutationException

Normalize three-letter and full residue names to their one-letter abbreviations. If a residue identity is passed in which does not fall into the set of canonical amino acids a MutationError is raised.

Parameters:

residue -

Returns:

Throws:

MutationException

populateAminoAcidOneToOneLookupMap

protected Map<String,String> populateAminoAcidOneToOneLookupMap()

getMutResidue

public char getMutResidue()

Return the mutant residue for this point mutation.

Returns:

getWtResidue

public char getWtResidue()

Return the wild-type residue for this point mutation.

Returns:

equals

public boolean equals(Object obj)

Two PointMutation objects are equal if their Position, WtResidue, and MutResidue values are all equal.

Overrides:

equals in class Mutation

Returns:

hashCode

public int hashCode()

Description copied from class: Mutation

To be overridden by subclasses

Overrides:

hashCode in class Mutation

toString

public String toString()

Override toString(), returns mutation as a string in wNm format

Overrides:

toString in class Mutation

Returns:

createPointMutationFrom_wNm

public static PointMutation createPointMutationFrom_wNm(String wNm)
                                                 throws MutationException

Create PointMutation from wNm-format, single-letter abbreviated mention. This wrapper function creates a PointMutation object from a mutation mention formatted in wNm-format, where w and m are the wild-type and mutant amino acids in their SINGLE-LETTER abbreviations, and N is an integer representing the sequence position.

Parameters:

wNm - a 3-character String representing a mutation mention in the wNm format

Returns:

Throws:

MutationException
