An oxacephem is a molecule similar to a cephem, but with oxygen substituted for the sulfur. They are synthetic compounds not seen in nature. Examples include moxalactam[1] and flomoxef.[2][3]

- Tripropeptin C (TPPC) is a natural calcium-ion-dependent lipopeptide antibiotic that inhibits peptidoglycan biosynthesis by binding to prenyl pyrophosphate. It displays very potent antimicrobial activity both in vitro and in a mouse model of methicillin-resistant Staphylococcus aureus (MRSA) septice

- Metallo-beta-lactamases (mbetals) are zinc-dependent enzymes that hydrolyze a wide range of beta-lactam antibiotics. The mbetal active site features an invariant Asp-120 that ligates one of the two metal ions (Zn2) and a metal-bridging water/hydroxide (Wat1). Previous studies show that substitutions
