EFI - Genome Neighborhood Tool

The Nugget

  • EFI-GNT is a web tool that analyzes genome neighborhoods in bacteria and fungi to provide insights into the metabolic function and activity of uncharacterized enzymes, increasing the confidence of predictions through a combination of sequence homology and genomic context information.

Key quotes

  • "Analysis of the genome neighborhood for an uncharacterized enzyme may provide genomic context, providing insights into its activity and metabolic function."
  • "The GNNs generated by EFI-GNT identify the protein families encoded by genes proximal to the input sequences, offering valuable information about the types of reactions catalyzed by the genome neighbors."
  • "The large-scale collection and organization of genome context enabled by EFI-GNT may allow the identification of enzymes in metabolic pathways that are not co-localized in the user’s 'target' organism."

Key insights

Introduction to Gene Clustering

  • Genes encoding metabolic pathways in bacteria and fungi are often co-localized in the genome.
  • Analysis of the genome neighborhood can offer insights into the activity and metabolic function of uncharacterized enzymes.
  • The combination of sequence homology and genome context information enhances the confidence of predictions.

Creating a Genome Neighborhood Network (GNN)

  1. Using SSN for Queries:

    • GNN organizes proteins encoded by the genome neighborhood for each query sequence based on Pfam family.
    • The GNNs identify protein families near the query sequences, providing information on the types of reactions catalyzed by these neighbors.
  2. Two GNN Formats:

    • SSN Cluster Hub-Nodes Format:
      • SSN clusters with query genes are central hubs in GNN, with neighboring Pfam families depicted as spoke-nodes.
      • Enables the identification of potential pathway members linked to query sequences and inference of reactions.
    • Pfam Family Hub-Nodes Format:
      • Each neighborhood Pfam family is central in a GNN cluster, with SSN clusters finding these families as neighbors depicted around them.
      • Helps assess if clusters in the query SSN are isofunctional and identifies members with different functions.
