Peptidoglycan O‐acetylesterase (Ape1), which is required for host survival in Neisseria sp., belongs to the diverse SGNH hydrolase superfamily, which includes important viral and bacterial virulence factors. Here, multi‐domain crystal structures of Ape1 with an SGNH catalytic domain and a newly iden...
