BeEM

BeEM converts mmCIF macromolecular structure files into Protein Data Bank (PDB) format to enable accurate format interoperability in structural biology workflows.

Key Features:

• Faithful Conversion: Retains all atomic coordinates and chain information when converting mmCIF to PDB, including chain identifiers longer than two characters.
• Speed Efficiency: Achieves conversion at least ten times faster than MAXIT and Phenix by avoiding unnecessary conversions between numerical values and text strings.
• Versatility: Handles mmCIF files with large atom counts and long chain identifiers without producing errors, supporting complex structural datasets.

Scientific Applications:

• Format interoperability: Enables use of legacy PDB-dependent bioinformatics tools by converting mmCIF structures into PDB while preserving structural detail.
• Data integrity in structural workflows: Preserves atomic- and chain-level information to prevent data loss or corruption when integrating structural datasets across platforms.

Methodology:

Directly parses mmCIF files and maps structural details into PDB records while bypassing intermediate numeric-to-text string conversions.
