Penicillin-binding protein 2 (PBP2) from N. gonorrhoeae is the major molecular target for β-
lactam antibiotics used to treat gonococcal infections. PBP2 from penicillin-resistant strains
of N. gonorrhoeae harbors an aspartate insertion after position 345 (Asp-345a) and 4-8
additional mutations, but how these alter the architecture of the protein is unknown. We have
determined the crystal structure of PBP2 derived from the penicillin-susceptible strain FA19,
which shows that the likely effect of Asp-345a is to alter a hydrogen-bonding network …
