Trypsin cleaving a hypothetical protein at sites of phosphorylation, liberating a series of C-terminally phosphorylated peptides (see Knight et al. p 1047). The image was provided by Zachhary Knight at University of California, San Francisco and was made using the graphics program InsightII, rendering the crystal structure of trypsin as a ribbon underneath a transparent Connelly surface. The substrate is rendered as ball and stick, the phosphate groups in red. Artwork rendered by Erin Boyle.
