BpForms: toolkit for concretely describing non-canonical DNA, RNA, and proteins

BpForms is a set of tools for concretely representing the primary structures of non-canonical forms of biopolymers, such as oxidized DNA, methylated RNA, and acetylated proteins, and calculating properties of non-canonical biopolymers.

BpForms encompasses five tools:

BpForms was motivated by the need to concretely represent the biochemistry of DNA modification, DNA repair, post-transcriptional processing, and post-translational processing in whole-cell computational models. BpForms is also a valuable tool for experimental proteomics and synthetic biology. In particular, we developed BpForms because there were no notations, schemas, data models, or file formats for concretely representing non-canonical forms of biopolymers, despite the existence of several databases and ontologies of DNA, RNA, and protein modifications, the ProForma Proteoform Notation, and the MOMODICS codes for modified RNA bases.

BpForms can be combined with BcForms to concretely describe the primary structure of complexes.

Installation

The following is a brief guide to installing BpForms. The Dockerfile in the repository contains detailed instructions for how to install BpForms in Ubuntu Linux.

  1. Install the third-party dependencies listed below.

  2. To use Marvin to calculate major protonation and tautomerization states, set JAVA_HOME to the path to your Java virtual machine (JVM)

    export JAVA_HOME=/usr/lib/jvm/default-java

  3. To use Marvin to calculate major protonation and tautomerization states, add Marvin to the Java class path

    export CLASSPATH=$CLASSPATH:/opt/chemaxon/marvinsuite/lib/MarvinBeans.jar

  4. Install this package

    • Install the latest release from PyPI:

      pip install bpforms

    • Install the latest revision from GitHub:

      pip install git+https://github.com/KarrLab/pkg_utils.git#egg=pkg_utils
pip install git+https://github.com/KarrLab/wc_utils.git#egg=wc_utils[chem]
pip install git+https://github.com/KarrLab/bpforms.git#egg=bpforms

    • To calculate major protonation and tautomerization states, BpForms must be installed with the [protontation] option:

      pip install bpforms[protontation]
pip install git+https://github.com/KarrLab/bpforms.git#egg=bpforms[protontation]

    • To draw molecules, BpForms must be installed with the [draw] option:

      pip install bpforms[draw]
pip install git+https://github.com/KarrLab/bpforms.git#egg=bpforms[draw]

    • To export the alphabets in OBO format, BpForms must be installed with the [onto_export] option:

      pip install bpforms[onto_export]
pip install git+https://github.com/KarrLab/bpforms.git#egg=bpforms[onto_export]

    • To install the rest API, BpForms must be installed with the [rest_api] option:

      pip install bpforms[rest_api]
pip install git+https://github.com/KarrLab/bpforms.git#egg=bpforms[rest_api]
