NOM azote

Package azote

        our @ISA = ("atome");
        The package inherits from the atome class


SYNOPSIS

        use azote;
        $new_atome = azote->new($nature, $x, $y, $z);
        print $new_atome->isSideChain();


DESCRIPTION

        new($nature, $x, $y, $z);
        Constructor.
        $new_atome =  azote->new($nature, $x, $y, $z);
        creates a new "azote" (nitrogen) object

setNature()

        Modifie l'attribut nature.

getNature()

        Recalls the atom nature

getTag()

        Returns 0 or 1 if N is NE2 of a GLN => means that the atom is not an acceptor, while NE2 of HIS is. So, if tag is 1, we bypass %PHYSICOCHIMIQUE

isSideChain()

        Returns 1 if the atom belongs to the side chain of a residue, else 0

VdWradius()

        Returns the Van der Waals radius

isHDonor()

        Returns 1 if the atom is hydrogen donor

isHAcceptor()

        Returns 1 if the atom is hydrogen acceptor

isPlus()

        Returns 1 if the atom is positive

isMoins()

        Returns 0 (ntirogens are not negative)
