Clicking on "Unmodified" loads the structure
for the non-mutated or unmodified enzyme.
Clicking on "Trp1" loads the
structure for the first mutant, "Trp2" loads the structure of the 2nd mutant,
Clicking on "Simple View" shows the backbone atoms, a bound substrate (Ala-Ala-Arg-Ala-Ala)
in thick sticks + spheres for atoms, and the sidechains of some important residues on the enzyme in thinner
- +/- Sub will add and remove the substrate.
- +/- Surf. on Sub will add or remove a gray surface on the substrate (be patient).
- +/- Surface on triad will place a yellow surface over the three residues in the catalytic triad.
- +/- Surface on #189 will place a red surface over the sidechain of residue 189.
