Figure 4. Conformational Changes in the MalK Subunits
(A
and B) Ribbon diagram of the MalK (A) open dimer in the
inward-facing structure and (B) closed dimer in the
outward-facing structure. The two NBDs are colored in green and
red, and the regulatory domains are colored in gray. The helical
subdomains are indicated and colored in light green or red. The
Walker A (WA) and the LSGGQ motifs are colored in blue and
yellow, respectively. ATP is shown in stick models.
(C)
Stereodiagram of MalK in the resting state. Using the regulatory
domains (gray) as the frame of reference, rotations of the two
NBDs (green and red) leading to the closed dimer are indicated.
