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.
Ah the nostalgia of science class.
