Fig. 1. Structure of E. coli GGT. (a) Ribbon drawing of the
GGT heterodimer. The L subunit is colored blue, and the S
subunit is colored green. (b) Ribbon drawing of the L subunit.
(c) Ribbon drawing of the S subunit. -Helices and -strands
are labeled. In each of the L and S subunits, the N terminus is
blue and the C terminus is red, with intermediate colors
following the distance in the sequence from the N terminus. The
N-terminal residue of the S subunit (Thr-391) is shown with a
stick model. (d) A topology diagram of E. coli GGT. Circle,
triangle, and square indicate -helix, -strand,
and insertion not conserved among Ntn-hydrolases, respectively.
The secondary structures were defined with DSSP (19). The
figures were prepared with PYMOL (20) and TOPS (21).
