Figure 4 Properties of the Mt ClpP1 tetradecamer. (a)
Superimposition of one heptamer from the Ec ClpP structure 1yg6
(molecular surface, gold) onto the heptamer of Mt ClpP1
structure 2cby (ribbons, blue) shows the greater compactness of
the latter. (b) Superimposition of monomer A of the Ec ClpP
structure 1yg6 onto monomer A of the Mt ClpP1 structure 2cby .
The superimposed monomers are on the right of the represented
heptamers. The colour scheme is as in (a). (c) Inwards rotation
of the monomers of Mt ClpP1 shown by overlaying monomer A from
(a) and (b). The axis of this rotation (in red) is approximately
perpendicular to the pore axis (in green). (d) Side view of the
front half surface of a complete model of Mt ClpP1, i.e.
including the region Leu126-Asp135, to illustrate the equatorial
pores. See text for details.
