Fig. 3. Interaction of the mitochondrial targeting
presequence of the ISP (subunit 9 in bright red) with the two
core subunits (core^ 1 in aqua blue and core 2 in green). (A)
Position of subunit 9 between the core 1 and core 2 subunits
viewed from the mitochondrial matrix side of the complex. The
cleaved NH[2]-terminal arm of the^ ISP is shown in magenta. The
 -sheet of
the NH[2]-terminal domain of core 2 is highlighted (yellowish
green), and the two possible^ Zn2+-binding sites are marked by
black arrowheads. (B) Stereoview of various interactions between
the COOH-terminal -strand of^
subunit 9 and its binding site in the core 2 subunit.
