Since 2014, PDB-101 has focused on different topics to help build a collection molecular stories around a particular theme. Past topics have included cancer and diabetes.

In 2025, PDB-101 will highlight the structural stories of Peak Performance: the structural biology of athletics and well-being, starting with a peak performance calendar on the structural biology of nutrition. 

The food that we eat contains four major classes of molecules–proteins, nucleic acids, lipids, and carbohydrates–as well as many micronutrients like vitamins and minerals. Our bodies contain thousands of different proteins that interact with and utilize these nutrients to build up our bodies and provide the energy we need to live. By understanding the structure and function of these protein-nutrient interactions, we can ensure that our body is performing at its peak. This knowledge informs the ways that we all can live our best lives, at all stages of our lives.

Holiday card caption:

Dopamine (yellow molecule) is released by our bodies when we do something pleasurable. The neurotransmitter binds to its receptors (white and red) which in turn activates the intracellular G-proteins. The activated G-proteins interact with other molecules to enable the signal to be relayed between different brain cells. Dopamine is also important in movement and motivation. Proper levels of dopamine allow our bodies to perform at their peak. PDB structures used for the dopamine receptor: 8uo2 and 6vms.
