ResiCon (Residue Contacts Analysis): Dynamic Domain Identification in Proteins

ResiCon identifies dynamic domains, hinges, and interfacial regions in proteins by analyzing residue contacts across ensembles of protein configurations to segment structures into relatively rigid dynamic domains.

Key Features:

• Data-Mining Analysis of Residue Contacts: Applies a data-mining strategy to evaluate residue–residue contacts across structural ensembles and detect regions with significant mobility or conformational change.
• Dynamic Domain Segmentation: Delineates compact dynamic domains based on contact patterns, enabling comparison with methods such as PiSQRD and GeoStaS.
• Validation on NMR and Molecular Dynamics Data: Evaluated using 30 NMR protein structures and molecular dynamics simulations of flap opening in HIV-1 protease.
• Functional Domain Detection: Identifies dynamic domains associated with conformational transitions, including functionally relevant regions in HIV-1 protease.

Scientific Applications:

• Protein Dynamics and Function Analysis: Characterizes conformational flexibility, domain motions, and structural transitions to support studies of protein function, drug design, and disease-related protein dysfunction.

Methodology:

Analyzes residue–residue contact patterns across multiple protein conformations, segments structures into rigid domains based on contact stability and variation, and identifies dynamic regions by detecting significant contact rearrangements within structural ensembles.
