Molecule of the Month
Posted on by Dr. Francis Collins
This lively interplay of shape and color is an artistic rendering of the Zika virus preparing to enter a cell (blue) by binding to its protein receptors (green). The spherical structures (pink) represent two Zika viruses in a blood vessel filled with blood plasma cells (tan). The virus in the middle in cross section shows viral envelope proteins (red) studding the outer surface, with membrane proteins (pink) embedded in a fatty layer of lipids (light purples). In the innermost circle, you can see the viral genome (yellow) coiled around capsid proteins (orange).
This image was sketched and hand-painted with watercolors by David Goodsell, a researcher and illustrator at The Scripps Research Institute, La Jolla, CA. Goodsell put paint and science to paper as part of the “Molecule of the Month” series run by RCSB Protein Data Bank (PDB), which NIH co-supports with the National Science Foundation and the Department of Energy. The PDB, which contains structural data on thousands of proteins and small molecules, uses its “Molecule of the Month” series to help students visualize a molecule or virus and to encourage their exploration of structural biology and its applications to medicine.
