The main-chain oxygen of Ser315 interacts with the amide nitrogen of aztreonam. Surprisingly, compared to the free MOX-1 structure, this main-chain carboxyl changes its position significantly upon binding aztreonam. This result indicates that the interaction between MOX-1 and beta-lactams can be accompanied by conformational changes of the B3 beta-strand main chain.
