Potato Defense Protein Nitration Data Against Phytophthora Infestans

92.7 KB of research data on peroxynitrite-mediated tyrosine nitration in potato defense against Phytophthora infestans, authored by Karolina Izbiańska-Jankowska and last updated on 2026-04-17. The data likely contains results from a potato–avr/vr Phytophthora infestans pathosystem model, including observations of nitrated protein accumulation within the first 6 hours post-inoculation. β-1,3-glucanase (PR-2) was identified as a main target of nitration, with functional studies showing its activity is inhibited by this modification.

Use Cases

• Study the temporal dynamics of protein nitration based on the described early (6 hpi) and delayed accumulation patterns in different pathosystems.
• Investigate the functional impact of tyrosine nitration on β-1,3-glucanase enzyme activity as described in the functional studies.
• Analyze potential regulatory sites like Tyr59 in the catalytic pocket based on the in silico structural analysis mentioned.
• Model the role of peroxynitrite-mediated post-translational modifications as a selective regulatory mechanism in plant immunity.

Strengths

• Data is associated with a specific, peer-reviewed research context investigating protein tyrosine nitration in plant immunity.
• The description provides a clear temporal framework, specifying observations within the first 6 hours post-inoculation.
• License is clearly defined as CC-BY-4.0, permitting reuse with attribution.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The primary data file is a 92.7 KB DOCX document, suggesting a limited scope likely focused on summary results or a data sheet rather than raw experimental data.
• Description metadata is limited; actual data structure and content require manual inspection after download.

Collection Method

Likely generated from laboratory experiments using a potato–avr/vr Phytophthora infestans system, two-dimensional gel electrophoresis, immunodetection, and recombinant protein functional studies.

Time Range

Experimental observations focus on early immune response, specifically within the first 6 hours post-inoculation.
