PilY1 Protein Diversity and Classification Across 67 Myxobacterial Genomes

An analysis of PilY1 protein diversity across 67 representative myxobacterial genomes, revealing an average of two homologs per genome. The dataset was created by Utkarsha Mahanta and last updated on May 7, 2026. It includes phylogenetic and structural modeling results to investigate the evolution and functional specialization of these bacterial adhesin proteins.

Use Cases

• Phylogenetic analysis of PilY1 protein clades based on taxonomy, domain architecture, and cysteine content mentioned in the description.
• Studying gene cluster conservation by examining the co-occurrence of pilY1 genes with minor pilins like pilX, pilW, pilV, and fimU.
• Investigating evolutionary mechanisms such as vertical inheritance versus horizontal gene transfer among PilY1 paralogs.
• Structural bioinformatics modeling of protein-protein interactions, specifically β-strand complementation between PilX and PilY1.

Strengths

• Analysis is based on 67 representative myxobacterial genomes, providing a defined taxonomic scope.
• Includes specific findings such as an average of two PilY1 homologs per genome and the identification of distinct evolutionary clades.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and redistribution.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (87.7 KB), indicating limited scope, likely containing summary or analysis results rather than raw genomic data.
