Computational modeling demonstrates accurate consensus structure inference across nucleic acid sequences, suggesting mutual information effectively maps molecular interactions.

Key Points

To develop an unsupervised statistical inference method capable of deducing higher-order secondary and tertiary consensus structures directly from nucleic acid sequence data.
Calculated position-position interdependence across sequence alignments using expected mutual information with an unbiased probability estimator to address zero observations at conserved sites.
Screened statistically significant interdependent position pairs using chi-square tests and filtered candidate pairs against known structural constraints.
Evaluated algorithm performance on aligned sequence datasets of transfer RNA (tRNA) and 5S ribosomal RNA (5S rRNA).
The mutual information framework effectively distinguished secondary and tertiary structural contact pairs from sequence alignments without requiring labeled structural training data.
Application to tRNA and 5S rRNA sequence benchmarks yielded high-accuracy consensus structural predictions of molecular interactions.
