Calcium-Dependent SctV-SctW Binding Affinity Data for Type III Secretion

A 636.6 KB Excel file contains data supporting a study on calcium's role in regulating bacterial type III secretion. The dataset, authored by Athina G. Portaliou and last updated in May 2026, likely includes measurements of protein binding affinities. It was shared under a CC-BY-4.0 license on figshare.

Use Cases

• Modeling the calcium-dependent switch in secretion substrate hierarchy based on the described molecular mechanism.
• Analyzing protein-protein interaction affinities between gatekeeper SctW and export apparatus component SctV.
• Investigating the effect of mutations on freezing the secretion receptor in high or low-affinity states.
• Studying the role of environmental calcium signals in regulating bacterial injectisome function.

Strengths

• Data is directly linked to a specific, peer-reviewed biological mechanism study.
• Shared under a permissive CC-BY-4.0 license for reuse.
• File size of 636.6 KB indicates a focused, manageable dataset.

Limitations

• Row count and specific column definitions are unknown, requiring manual inspection after download.
• Description metadata is limited; actual data quality and completeness require verification.
• The dataset's scope is limited to the specific proteins and interactions described in the accompanying study.
