Plasmodium Enzyme Phosphoethanolamine Methyltransferase (image)
Caption
A cartoon based on the electron density map makes it easier to see the protein's structure and figure out how it works. The enzyme's job is to add a methyl group -- three times -- to a starting molecule as part of a process for making cell membranes. In this cartoon, the phosphate is a stand-in for the starting molecule and the green molecule is the one that donates a methyl group. Both are positioned in the active site of the enzyme, the pocket where the chemistry takes place.
