BcForms

BcForms describes macromolecular complexes and their chemical composition to represent non-canonical residues, caps, crosslinks, circular topologies, and nicks for use in molecular characterization and data exchange.

Key Features:

• Grammar-based representation: Provides a robust grammar for describing macromolecular complexes and their topologies, including non-canonical monomeric forms and circular structures.
• Molecular scope: Represents DNA, RNA, protein subunits, and small molecular components within the same descriptive framework.
• Notation interoperability: Utilizes BpForms for nucleic acids and proteins and SMILES for small molecules to encode component structures.
• Modification and linkage representation: Encodes non-canonical residues, caps, crosslinks, and nicks explicitly within macromolecular descriptions.
• Physical-property computation: Computes molecular structure-derived properties including chemical formula, molecular weight, and net charge.
• Validation: Verifies macromolecular descriptions to enable quality control of molecule representations.
• Standardization for exchange: Produces standardized descriptions to facilitate exchange of detailed macromolecular information.

Scientific Applications:

• Omics Research: Ensures accuracy and standardization of macromolecular data to support data integration and sharing in omics studies.
• Systems Biology: Supports construction of cellular and network models that include complex molecular species and post-translational modifications.
• Bioengineering: Enables precise specification of molecular configurations for design and engineering of biological systems.

Methodology:

Implements a formal grammar (BcForms/BpForms) and uses SMILES for small molecules to represent components, and performs verification and computation of physical properties such as structure, formula, molecular weight, and charge.
