PotatoPepDB
A curated database and analysis platform for antimicrobial peptides from Solanum tuberosum.
PotatoPepDB is a bioinformatics platform for discovering, modeling, and analyzing antimicrobial peptides (AMPs) derived from potato. It combines a searchable peptide repository with physicochemical analysis tools, a BLAST-style alignment engine, and interactive data visualization.
Built for plant-biotech researchers working on bio-pesticides and disease-resistant crops, it makes natural plant-defense molecules easy to explore — no login required.
Features
Simple & Advanced Search
Search by name, sequence, accession, tissue, activity, or molecular properties with logical filters.
Physicochemical Calculator
Real-time MW, pI, net charge, GRAVY, Boman index, hydrophobic ratio, and instability index.
BLAST-Style Alignment
Smith-Waterman local alignment against the database with E-value and identity scores.
Statistics Dashboard
Interactive pie, bar, and scatter charts for tissue, activity, and charge-hydrophobicity analysis.
3D Structure Viewer
NGL.js molecular visualization with PDB structures and RCSB integration.
Multi-Format Export
Download peptide data and structures as JSON, CSV, FASTA, or PDB.
FASTA Bulk Import
Admin batch import of peptides from FASTA files.
Curated Reference Data
Reference potato peptides (Snakin-1/2, defensins, Kunitz inhibitors) ready to explore.
Open Access
Fully public database — no paywall, no login for browsing or analysis.
