ABSTRACT
|
|
|
| |
|
Native thermolysin binds a single catalytically essential zinc ion that is
tetrahedrally coordinated by three protein ligands and a water molecule. During
catalysis the zinc ligation is thought to change from fourfold to fivefold.
Substitution of the active-site zinc with Cd2+, Mn2+, Fe2+, and Co2+ alters the
catalytic activity (Holmquist B, Vallee BL, 1974, J Biol Chem 249:4601-4607).
Excess zinc inhibits the enzyme. To investigate the structural basis of these
changes in activity, we have determined the structures of a series of
metal-substituted thermolysins at 1.7-1.9 A resolution. The structure of the
Co(2+)-substituted enzyme is shown to be very similar to that of wild type
except that two solvent molecules are liganded to the metal at positions that
are thought to be occupied by the two oxygens of the hydrated scissile peptide
in the transition state. Thus, the enhanced activity toward some substrates of
the cobalt-relative to the zinc-substituted enzyme may be due to enhanced
stabilization of the transition state. The ability of Zn2+ and Co2+ to accept
tetrahedral coordination in the Michaelis complex, as well as fivefold
coordination in the transition state, may also contribute to their effectiveness
in catalysis. The Cd(2+)- and Mn(2+)-substituted thermolysins display
conformational changes that disrupt the active site to varying degrees and could
explain the associated reduction of activity. The conformational changes involve
not only the essential catalytic residue, Glu 143, but also concerted side-chain
rotations in the adjacent residues Met 120 and Leu 144. Some of these side-chain
movements are similar to adjustments that have been observed previously in
association with the "hinge-bending" motion that is presumed to occur during
catalysis by the zinc endoproteases. In the presence of excess zinc, a second
zinc ion is observed to bind at His 231 within 3.2 A of the zinc bound to native
thermolysin, explaining the inhibitory effect.
