Biochemical research on methane oxidation in anaerobic methanotrophic archaea is hampered by the lack of cultured isolates. Here, Müller et al. present atomic-resolution snapshots of the methane-oxidising enzymes purified from enrichment cultures, providing molecular insights into the process and revealing unusual post-translational modifications.
