# Bio::Variation::AAReverseMutate(3pm)

point mutation and codon information from single amino acid changes

## NAME

Bio::Variation::AAReverseMutate - point mutation and codon\
   information from single amino acid changes

## SYNOPSIS

```
    $aamut = Bio::Variation::AAReverseMutate->new
                 (-aa_ori => 'F',
                  -aa_mut => 'S',
                  -codon_ori => 'ttc', # optional
                  -codon_table => '3'  # defaults to 1
                  );
   @points = $aamut->each_Variant;
   if (scalar @points > 0 ) {
       foreach $rnachange ( @points ) {
           # $rnachange is a Bio::Variation::RNAChange object
           print " ", $rnachange->allele_ori->seq, ">",
           $rnachange->allele_mut->seq, " in ",
           $rnachange->codon_ori, ">", $rnachange->codon_mut,
           " at position ", $rnachange->codon_pos, "\n";
       }
   } else  {
       print "No point mutations possible\n",
   }
```

## DESCRIPTION

Bio::Variation::AAReverseMutate objects take in reference and mutated amino acid information and deduces potential point mutations at RNA level leading to this change. The choice can be further limited by letting the object know what is the the codon in the reference sequence. The results are returned as Bio::Variation::RNAChange objects.

## FEEDBACK

### Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the  Bioperl mailing lists  Your participation is much appreciated.

```

### Support

Please direct usage questions or support issues to the mailing list:

*bioperl-l@bioperl.org*

rather than to the module maintainer directly. Many experienced and  reponsive experts will be able look at the problem and quickly  address it. Please include a thorough description of the problem  with code and data examples if at all possible.

### Reporting Bugs

## APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a \_

### aa\_ori

```
 Title   : aa_ori
 Usage   : $obj->aa_ori();
 Function:
            Sets and returns original aa sequence.  If value is not
            set, returns false.
            Amino acid sequences are stored in upper case characters,
            others in lower case.
 Example :
 Returns : string
 Args    : single character amino acid code
```

### aa\_mut

```
 Title   : aa_mut
 Usage   : $obj->aa_mut();
 Function:
            Sets and returns the mutated allele sequence.  If value is not
            set, returns false.
 Example :
 Returns : string
 Args    : single character amino acid code
```

### codon\_ori

```
 Title   : codon_ori
 Usage   : $obj->codon_ori();
 Function:
            Sets and returns codon_ori triplet.  If value is not set,
            returns false.  The string has to be three characters
            long. The character content is not checked.
 Example :
 Returns : string
 Args    : string
```

### codon\_table

```
 Title   : codon_table
 Usage   : $obj->codon_table();
 Function:
            Sets and returns the codon table id of the RNA
            If value is not set, returns 1, 'universal' code, as the default.
 Example :
 Returns : integer
 Args    : none if get, the new value if set
```

### each\_Variant

```
 Title   : each_Variant
 Usage   : $obj->each_Variant();
 Function:
            Returns a list of Variants.
 Example :
 Returns : list of Variants
 Args    : none
```
