Figure 1. Structural environment of Glu230. The D-helix, F-helix, catalytic loop, P+1 loop, and part of the inhibitory peptide IP20 are shown in ribbon diagram. Glu230 is located at the C-terminal end of the F-helix. P-2 Arg from IP20 is rendered as ball-and-sticks. Dotted lines represent interactions between Glu230 and its environment.
