Figure 1. Structural comparison of K698M mutant to other  Pg
( Pm)
crystal structures. In the middle, a ribbon diagram of K698M
structure is shown in stereo view, flanked by diagrams of
comparisons of local backbone traces. Fourteen previously
published Pg
( Pm)
crystal structures from six crystal forms are superimposed onto
the K698M structure by overlaying their C[  ]atoms
(using a 3-Å cutoff). The K698M structure (PDB file 1RJX)
is colored in blue, Pm
structures (1BML and 1BUI) in yellow, free Pg
(1DDJ and 1QRZ) in green, and other Pg
(1L4D and 1L4Z) in magenta. In the stereo diagram, positions of
the K698M mutation and the catalytic Ser-741(195) are marked
with yellow and green spheres, respectively.
