Frataxin (human) mitochondrial protein. Reduced expression causes Friedreich's ataxia. 3D illustration. Cartoon & wireframe representation.
graphs and cells
Amylase protein (3d structure). Digestive enzyme, responsible for the hydrolysis of starch into sugars. Found in saliva.
This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.
Colorful chain of amino acids or bio molecule called proteins - 3d illustration
3D realistically coloured hexagonal shapes of connected spheres, background with copy space. Futuristic illustration design template for scientific presentation. Molecular business, science, teamwork concept.
Proliferating cell nuclear antigen (PCNA) is a DNA clamp that acts as a processivity factor for DNA polymerase δ in eukaryotic cells and is essential for replication. PCNA is a homotrimer and achieves its processivity by encircling the DNA, where it acts as a scaffold to recruit proteins involved in DNA replication, DNA repair, chromatin remodeling and epigenetics. 3D cartoon and Gaussian surface models, chain instance color scheme, based on PDB 3wgw, white background.
Computer generated 3D abstract forms.\n\nNote: This image is less than one year old, and is  not available for use anywhere else. I created it on Blender 3.0.1,  and that is the reason it has no EXIF data. I uploaded in a property release section a screenshot of processing the composition on Blender on my PC. Date of creation is 01/11/2022.
The coronavirus 3CL hydrolase enzyme is essential for the maturation of the virus. It can be a promising target for drugs that would inhibit cleavage of the viral polyprotein and prevent spread of the infection. Source: PDB entry 6LU7
Background created by fractal geometry.
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
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.
Low-Fiber Diet Risks Gut Health & Allergies
A ball and stick + ribbons model of Bowman-Birk Protease Inhibitor, more commonly abbreviated to BBI. It is used clinically to treat and help prevent cancer.
3D cartoon and Gaussian surface models, PDB 2e5d, white background
Molecular model of lactose, a disaccharide sugar in milk.
Proteasomes are large molecular machines that degrade unneeded or damaged proteins that have been tagged with polyubiquitin.
Background created by fractal geometry.
Indoleamine 2,3 dioxygenase 1 (IDO1) protein. Tryptophan catabolic enzyme of the kynurenine pathway. 3D illustration.
Crystal Lattice
Anthrax oedema factor. Molecular model of oedema factor (EF) from the anthrax bacterium Bacillus antracis complexed with a calmodulin protein molecule. EF is one of three protein components that form the anthrax toxin. It is an enzyme that interferes with water homeostasis, leading to the accumulation of fluid in the tissues. Anthrax most commonly affects cattle, sheep and goats, but can also infect humans.
A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
