MCTBI

MCTBI predicts metal ion effects on RNA structures by incorporating ion correlation and fluctuation effects to improve predictions of ion binding distributions and electrostatic free energies.

Key Features:

• Ion correlation and fluctuation effects: Accounts explicitly for ion correlation and fluctuation effects to enhance accuracy over traditional mean-field approaches.
• Multivalent ion predictions: Predicts effects of multivalent ions such as Mg2+ on RNA structure formation and stability.
• Comprehensive output metrics: Reports metal ion binding fractions, most probable bound ion distributions, electrostatic free energy of the system, and its components.

Scientific Applications:

• RNA biochemistry and structural biology: Provides quantitative predictions of how metal ions modulate RNA structure and interactions.
• Mechanistic studies of folding and stability: Offers mechanistic insight into the influence of metal ions on RNA folding pathways and thermodynamic stability.
• Rational design of RNA structures: Informs design efforts in drug development, synthetic biology, and genetic engineering by predicting ion-dependent structural effects.

Methodology:

MCTBI implements a theoretical model that integrates ion correlation and fluctuation effects into predictions and has been validated through theory–experiment comparisons.
