Metalloproteases can often be recognised by the presence of a short conserved signature sequence containing two histidines. This characteristic motif is most typically HEXXH or HXXEH, but several classes of amidohydrolases have now been identified that contain an HxH motif. With the exception of urease-type amidohydrolases, HxH metalloproteases are not well characterized mechanistically, and even the identity of the metal, its ligands and coordination geometry are unknown in many cases. We propose (a) to express, purify and characterize a series of bacterial HxH proteases (b) to determine their structure by X-ray crystallography and (c) to synthesize phosphinic acid, phosphonate ester and hydroxamate based substrate analogues/inhibitors for mechanistic studies.
