RuBisCo protein structure

Nice design of the protein structure of the lactata dehydrogenase, which catalyses the conversion of lactate to pyruvate in the last step of glycolysis.

Structure of the CaMKII holoenzyme

Cholera toxin is an exotoxin that causes cholera.

The hERG channel is responsible for the repolarizing potassium ion flow in the heart during heart excitation.

Structure of the ATP synthase

Structure of GFP

A cross-section of a eukaryotic cell (neuron).

Scientifically accurate representation of a cross-section of a neuron (nerve cell) axon. Microtubules, vesicles, and other macromolecular structures can be seen.

The hERG channel is responsible for the repolarizing potassium ion flow in the heart during heart excitation.

Structure of the ATP synthase

Aquaporin Z (AqpZ) is an integral membrane protein that allows the transport of 3 billon water molecules per second across the membrane. Aquaporin Z (AqpZ) is a aquaporine from E. coli.

Antibodies in action. Artwork of antibodies (light to dark pink) in blood attacking an invading bacterium (left) and virus particle (centre right, green). Antibodies are Y-shaped proteins made by the immune system in response to infection by bacteria, viruses or allergens. Each antibody is made to recognise a specific target antigen and bind themselves to the surface. Binding can neutralize toxins or invading organisms and prevent them from interfering with normal cell processes. Binding can also make it easier for white blood cells to recognise and digest foreign particles.
