Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
Infinity sign made out of multiple spheres and circular shapes against grey background.
CD47 also known as integrin associated protein is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 and signal-regulatory protein alpha. 3D cartoon and Gaussian surface models, chain id color scheme, based on PDB 2jjt, white background
In vitro bacterial culture
The structure of the protein molecule, tumor marker glioblastoma. X-ray crystalline model of the protein encoded by the MELK gene. 3D rendering.
Serratia Marcescens is a rare Nosocomial Pathogen.\nThis bacterium is a gram-negative bacillus  found in soil and water. it produces a red pigment at room temperature. It can cause urinary and respiratory infections, endocarditis, osteomyelitis, septicemia, wound infections, eye infections, and meningitis.
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
Organic objects form a triangle. Artificial space incorporating organic materials.\nThis work was policy within one month. It is also an original work for this brief and cannot be used elsewhere.
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
Red cellular tissue, executives and pill-shaped pills
3D cartoon and Gaussian surface models, PDB 6vg8, white background
Inside protein molecule
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Abstract geometric shape
Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
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.
PETase (left) degrades  polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA).
Artificial molecular structure in many colors. Horizontal composition, isolated on white background.
3D cartoon and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Rendered Remdesivir molecule in 3D, an experimental drug from Gilead, used to cure the first case of 2019-nCoV in the United States (for a patient at Seattle, Washington). The model showed accurate atom connection and stereochemistry, which was professionally checked. Color symbols - light blue=carbon, red=oxygen, blue=nitrogen, white=hydrogen, green=phosphorus
Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
