NAME

Bio::Tools::ECnumber - representation of EC numbers (Enzyme Classification)

SYNOPSIS

  use Bio::Tools::ECnumber;

  # Creation of ECnumber objects
  my $EC1 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.1" );
  my $EC2 = Bio::Tools::ECnumber->new( -ec_string => "EC 1.1.1.1" );
  my $EC3 = Bio::Tools::ECnumber->new();

  # Copying
  my $EC4 = $EC1->copy();

  # Modification/canonicalization of ECnumber objects
  print $EC3->EC_string( "1.01.01.001" ); # Prints "1.1.1.1".

  # Stringify
  print $EC3->EC_string();
  # or
  print $EC3->to_string();

  # Test for equality
  # -- Against ECnumber object:
  if ( $EC3->is_equal( $EC2 ) ) { # Prints "equal".
      print "equal";
  }
  # -- Against string representation of EC number:
  if ( ! $EC3->is_equal( "1.1.1.-" ) ) { # Prints "not equal".
      print "not equal";
  }

  # Test for membership
  my $EC5 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.-" ); 
  # -- Against ECnumber object.
  if ( $EC1->is_member( $EC5 ) ) { # Prints "member".
      print "member"; 
  }
  # -- Against string representation of EC number.
  if ( ! $EC1->is_member( "4.3.1.-" ) ) { # Prints "not member".
      print "not member";
  }

DESCRIPTION

Bio::Tools::ECnumber is a representation of EC numbers, the numerical hierarchy for Enzyme Classification.

APPENDIX

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

new

 Title   : new
 Usage   : $EC1 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.1" );
           or
           $EC2 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.2",
                                             -comment   => "Is EC 4.3.2.2" );
           or                      
           $EC3 = Bio::Tools::ECnumber->new(); # EC3 is now "-.-.-.-"                      
 Function: Creates a new ECnumber object.
           Parses a EC number from "x.x.x.x", "EC x.x.x.x",
           "ECx.x.x.x", or "EC:x.x.x.x";
           x being either a positive integer or a "-".
 Returns : A new ECnumber object.
 Args    : A string representing a EC number, e.g. "4.3.2.1"
           or "EC 4.3.2.1" or "1.-.-.-".

init

 Title   : init()
 Usage   : $EC1->init(); # EC1 is now "-.-.-.-"    
 Function: Initializes this ECnumber to default values.
 Returns : 
 Args    :

copy

 Title   : copy()
 Usage   : $EC2 = $EC1->copy();
 Function: Creates a new ECnumber object which is an exact copy
           of this ECnumber.
 Returns : A copy of this ECnumber.
