"""
Methoxyphenylthiobutanol (MPTB) moiety.

This module defines the `MPTB` class, representing a methoxyphenylthiobutanol functional group
for molecular simulations. The MPTB group includes ports for molecular assembly.

Examples
--------
>>> from mbuild_polybuild.aa_functional_groups.mptb import MPTB
>>> mptb = MPTB()
>>> mptb.save("methoxyphenylthiobutanol.mol2", overwrite=True)

    A methoxyphenylthiobutanol (MPTB) group.

    This class initializes a methoxyphenylthiobutanol functional group by loading its structure
    from a PDB file and setting up its ports for molecular assembly.

    Ports
    -----
    - `port[0]`: Connection to the methoxy group.
    - `port[1]`: Connection to the phenyl group.
    - `port[2]`: Connection to the butanol group.

    --------
