Nature Communications publishes a steady stream of peptide-relevant primary research — typically mechanism work, structural biology, and AI-driven discovery papers that don't fit the broader Nature flagship. The journal is a regular source on this site for de novo peptide design, antimicrobial peptide work, peptide-drug conjugate chemistry, and structural studies on intracellular protein–protein interaction targets.
Representative pieces covered here: AI-discovered antimicrobial scaffolds, structural work on macrocyclic peptide binding to undruggable targets, bicyclic peptide chemistry from Bicycle Therapeutics and academic collaborators, and HLB Innovation's HMD-AMP transformer-based AMP discovery work.

A Nature Communications paper introduces CAMPER (Constraint-driven AMP Engineering with Ranking), a mechanistic AI framework that integrates machine learning with biophysical ranking to design membrane-targeting peptides against MRSA persisters and biofilms. The framework identified WP-CAMPER1, a 12-mer peptide that kills S. aureus MW2 at an MIC of 4 µg/mL; a 2% topical formulation reduced S. aureus burden by 2.5 log10 in a murine skin infection model.
A Nature Communications paper describes peptide dendron nanoassemblies that shape-shift in response to bacterial enzymes to eradicate intracellular drug-resistant bacteria while protecting host macrophages. The nanoassemblies combine self-assembling regions, cell-penetrating motifs, enzyme-responsive sequences, and integrin-targeting ligands, transforming from nanoparticles to nanofibers for prolonged cell retention before converting back to nanoparticles for cellular uptake.
A Nature Communications paper published April 15 reveals shared structural mechanisms between SbmA — an E. coli membrane transporter that imports antimicrobial peptides — and ABC transporters. Using cryo-electron microscopy, EPR spectroscopy, and molecular dynamics simulations, researchers demonstrated SbmA undergoes ABC-transporter-like conformational changes, informing strategies to design antibiotic-resistant-bacteria-penetrating peptide drugs.
