Controllable AMP Design — Curated E. coli MIC Dataset

10,044 curated antimicrobial peptide (AMP) sequences paired with a continuous minimum inhibitory concentration (MIC) activity score against E. coli, cleaned and deduplicated from DBAASP v3. Used to train the CVAE generator and Judge predictor in Sloudis/controllable-amp-design (GitHub repo).

This is the cleaned/derived dataset only. The raw DBAASP bulk exports it was built from are not redistributed here — their redistribution terms are unclear, so if you want to reproduce the cleaning pipeline from scratch, pull your own exports from dbaasp.org and run src/data/clean.py from the GitHub repo.

Curation pipeline

Starting from raw DBAASP activity + peptide-metadata exports:

1. 1.Filter to MIC assays against E. coli, monomeric linear peptides with a known sequence
2. 2.Parse free-text MIC values (numbers, inequalities, ranges, ± notation) into a single float
3. 3.Standardize units to µM (µg/mL converted via computed monoisotopic molecular weight)
4. 4.Restrict to the 20 standard amino acids, length 5–50
5. 5.Deduplicate by sequence, taking the geometric mean of MIC across repeated measurements
6. 6.log10-transform MIC

See src/data/clean.py in the GitHub repo for the exact implementation.
