The discovery of unreported antimicrobial resistance genes (ARGs) remains essential. Here, we report the identification and preliminary characterization of an α/β-hydrolase that inactivates macrolides. This serine-dependent macrolide esterase co-occurs with emerging ARGs in the environment, animal microbiomes, and pathogens.
