For most of human history, smallpox was a serious threat to human life. With discovery of vaccines based on the similar, less dangerous vaccinia virus, this changed, and a global public health effort has eradicated smallpox from the face of the Earth. Other poxviruses, such as monkeypox and cowpox, are still causing rare, localized infections. These are often the result of transfer of the virus from animals to humans.
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.
