Cyano-bacteria obtain energy from photosynthesis. To optimize their life processes and energy production during the illuminated portion of the day, they utilize a circadian system. The animation presents a simplified view of the protein-protein interactions in the cyano-bacterial circadian system using the PDB structures 5n8y and 2gbl. Read the Molecule of the Month on Circadian Clock Proteins to learn how they measure time in our cells.
PDB-101 helps teachers, students, and the general public explore the 3D world of proteins and nucleic acids. Learning about their diverse shapes and functions helps to understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease to biological energy.
Why PDB-101? Researchers around the globe make these 3D structures freely available at the Protein Data Bank (PDB) archive. PDB-101 builds introductory materials to help beginners get started in the subject ("101", as in an entry level course) as well as resources for extended learning.
