Standard residues in MDAnalysis selections
==========================================

.. _protein-selection:

Proteins
========
The residue names listed here are accessible via the "protein" keyword in the :ref:`selections`.

The below names are drawn from the CHARMM 27, OPLS-AA, GROMOS 53A6, AMBER 03, and AMBER 99sb*-ILDN force fields.

.. include:: generated/selections/protein.txt

----------------
Protein backbone
----------------

Protein backbone atoms in MDAnalysis belong to a recognised protein residue and have the atom names:

.. include:: generated/selections/protein_backbone.txt

.. _nucleic-selection:

Nucleic acids
=============

The residue names listed here are accessible via the "nucleic" keyword in the :ref:`selections`.

The below names are drawn from largely from the CHARMM force field.

.. _nucleobase-selection:

-----------
Nucleobases
-----------

Nucleobase atoms from nucleic acid residues are recognised based on their names in CHARMM.

.. include:: generated/selections/base.txt
