Genome mining for methanobactinsResults: The potential for Mbn production in a wider range of bacterial species was assessed by mining microbial genomes. Operons encoding Mbnlike precursor peptides, MbnAs, were identified in 16 new species, including both methanotrophs and, surprisingly, nonmethanotrophs. Along with MbnA, the core of the operon is formed by two putative ...
