Figure 4. Active site details. AtKAT sections are shown in
stick-mode with atomic positions, C colored grey, N blue, O red
and S orange, with hydrogen bonding interactions (distances <3.4
Å) as blue broken lines. (a) Hydrogen bonding associated
with a buried water molecule, a blue sphere, which binds Cys425.
(b) The environment of His393. Helix α4 is depicted as a
yellow ribbon. Figure 4. Active site details. AtKAT sections
