Chemical data format Protein report format Textual format BcForms text/plain 1.24 BcForms is related to http://edamontology.org/format_3909. (BcForms uses BpForms to describe subunits which are DNA, RNA, or protein polymers.) However, that format isn't the parent of BcForms. BcForms is similarly related to SMILES (http://edamontology.org/data_2301). BcForms is a format for abstractly describing the molecular structure (atoms and bonds) of macromolecular complexes as a collection of subunits and crosslinks. Each subunit can be described with BpForms (http://edamontology.org/format_3909) or SMILES (http://edamontology.org/data_2301). BcForms uses an ontology of crosslinks to abstract the chemical details of crosslinks from the descriptions of complexes (see https://bpforms.org/crosslink.html).
