Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria. Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.

Taq polymerase PCR enzyme: a heat-stable DNA polymerase protein that is the key component that makes the polymerase chain reaction (PCR) possible, which is essential for DNA cloning and sequencing
Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.
Calmodulin is an intracelular target of calcium ions. Once activated by Ca2+ (red), calmodulin interacts with various target proteins such as kinases and phosphatases.. It plays an important role in long-term memory. and muscle contraction. CaM has 4 calcium binding sites. PDB entry 3CLN, 1CFD
