MetBP

MetBP detects and analyzes interactions between metal ions and RNA base pairs to characterize binding geometry and secondary-structure context.

Key Features:

• Metal Ion Detection: Identifies metal ions that bind to nucleobases involved in base pairs and reports the interacting nucleotide partners.
• Input Compatibility: Accepts structure files in mmCIF and PDB formats.
• Detailed Reporting: Reports binding distances and angles and provides geometric parameters for metal–nucleotide interactions.
• Base Pair Stability Analysis: Evaluates the stability of base pairs influenced by metal ion binding.
• Secondary Structure Information: Annotates secondary-structure context (helix, loop, unpaired) for residues where metals bind.
• Generalized Application: Detects metal-binding sites in proteins and DNA in addition to RNA.

Scientific Applications:

• Structural biology of nucleic acids and proteins: Provides site-specific metal–RNA interaction data for structural studies.
• Gene regulation and enzymatic activity: Characterizes metal-mediated effects on RNA structure relevant to regulation and catalysis.
• Molecular stability analysis: Assesses how metal binding influences RNA base-pair stability.

Methodology:

Computes base pairs from provided structural data, identifies metal ions binding to those nucleotides, and generates reports including geometric parameters and secondary-structure context; operates without reliance on other software tools.
