Google AI selects 97 amino acid antimicrobial peptide candidates... undergoing laboratory verification

Google DeepMind said its AI agent identified a candidate antimicrobial peptide 97 amino acids long from the respiratory pathogen Streptococcus pseudopneumoniae, disclosed in an October 15 technical demonstration using Google Antigravity. Researchers screened millions of functionally unclassified protein sequences in the public UniProt database to find the candidate, which is now undergoing laboratory validation. The work matters because antimicrobial peptides can inhibit bacterial growth and represent a potential new class of compounds against respiratory infections amid rising antibiotic resistance. Watch for lab results confirming or refuting the peptide's activity, and for whether the agent-based screening approach generalizes to other pathogens.
