RINerator

News

A new version of RINerator is released.
In particular, it computes conservation scores from a user-specified multiple sequence alignment (details), retrieves biochemical amino acid properties from external resources (details), and generates RINs compatible with Cytoscape 3.x and RINalyzer 2.x (details).


Description

RINerator generates user-defined RINs from a 3D protein structure and enriches them with additional biochemical information. In contrast to previous simplistic interaction definition approaches based on spatial atomic distance between residues, RINerator enables a more realistic representation by considering different biochemical interaction types, such as hydrogen bonds and interactomic contacts, and even quantifying the strength of individual interactions. Furthermore, RINerator can calculate conservation scores from a user-specified multiple sequence alignment and retrieve biochemical amino acid properties from external resources, such as AAindex and ConSurfDB. The resulting networks and accompanying data can be visualized in Cytoscape using the RINalyzer and structureViz apps.

Figure 1

Residue interaction network constructed for a selection of residues from the 3D structure of yeast TIM (PDB: 2YPI) and additional information annotated to the nodes. The network is visualized in Cytoscape using the structureViz and RINalyzer apps, while the structure is displayed by UCSF Chimera. The network nodes and the corresponding residues are colored according to their conservation score (turquoise-to-pink coloring indicates variable-to-conserved sites). The network edges represent non-covalent residue interactions (blue for contacts and red for hydrogen bonds).
