Watercolor Illustration by David S. Goodsell,

In collaboration with Field Test Independent Film Corps, I created a painting of an entire Mycoplasma mycoides cell. The cell shown here is about 250 nanometers in diameter, which is at the small end of the range of observed sizes.
As in my other work, I have tried to include all of the macromolecules at reasonable locations and concentrations, and with the actual shapes and sizes.
Small molecules like sugars, ATP and water are not shown.

[This is a microorganism that lives in cattle and goats, causing lung disease.]
A transposase molecule is the enzyme that cuts out pieces of DNA and moves it to a different place on the DNA strand, in a process known as transposition.
To create this image the molecule data was downloaded from the Protein Data Bank website and loaded into the Visual Molecular Dynamics (VMD) program. This program allows you to view molecules in a variety of different visual representations, and to separate different parts of the molecule such as bonds, proteins, and water. This molecule was separated into protein and non-protein parts. The protein section (multicolored) was saved in two different versions: a ‘cartoon’ version, and a ‘cloud’ version. The non-protein (teal) part of the molecule is actually a section of the DNA strand. Each piece of the molecule was then saved as a separate bitmap image and composited together in Adobe photoshop.
