3D cartoon and Gaussian surface models. PDB 2aai, white background.
Lactose-negative biofilm-forming Enterobacter cloacae, resistant to multiple drugs.  Enterobacter cloacae is a member of the normal gut flora. These bacteria are responsable for many hospital-acquired infections for which the mortality rate is generally high.
The structure of the protein molecule, tumor marker glioblastoma. X-ray crystalline model of the protein encoded by the MELK gene. 3D rendering.

PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.
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.

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.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Molecular Model of Vitamin E.
PETase (left) degrades  polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.
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.

Life-threatening infections are on the rise due to drug-resistant bacteria. Carbapenemase-producing organisms (CPO) are bacteria that have become resistant to a group of antibiotics known as carbapenems. CPO are emerging pathogens world wide.
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
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
