Publication Abstract from PubMed
Lactivicin (LTV) is a natural non-beta-lactam antibiotic that inhibits penicillin-binding proteins and serine beta-lactamases. A crystal structure of a BS3-LTV complex reveals that, as for its reaction with PBPs, LTV reacts with the nucleophilic serine and that cycloserine and lactone rings of LTV are opened. This structure, together with reported structures of PBP1b with lactivicins, provides a basis for developing improved lactivicin-based gamma-lactam antibiotics.
