Peptide Residue Volumes in HLA II DR Structures

Alexander E. Kister published a dataset on figshare in April 2026 detailing peptide residue volumes in HLA II DR protein structures. The dataset likely contains tabular data with residue volumes in cubic angstroms categorized by size groups and summary statistics for each peptide position. The file is 25.7 KB in size.

Use Cases

• Analyze residue volume distributions across peptide positions based on categorized size groups.
• Identify common volume category pairs in specific positions based on the 'most common pair' feature.
• Calculate total peptide volumes based on the 'Total volume' column mentioned in the description.
• Compare structural variability across HLA II DR complexes based on residue volume statistics.

Strengths

• Data is structured with explicit volume measurements in cubic angstroms (A³).
• Includes categorical grouping of residues into five distinct size categories.
• Provides summary statistics like 'most common pair' and percentage calculations for each position.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Dataset is very small (25.7 KB), indicating limited scope.
