-One obvious test of this hypothesis is an ability of these sequences to impart instability on an otherwise stable protein. To test this hypothesis, we constructed a plasmid (pKSD-PRP) expressing a chimeric gene encoding the first 40 amino acids of UmuD fused to a 7-amino-acid linker joined to the entire Streptoalloteichus hindustanus Ble protein.
-The S. hindustanus ble gene encodes a small, stable protein that provides resistance to the antibiotics of the phleomycin family.
-Furthermore, subsequent experimentation demonstrated that residues 1-29 of UmuD are sufficient to impart Lon recognition and degradation of the PRP similar to that seen with the 40-amino-acid fusion.
-The amino-terminal 40 amino acids of UmuD are sufficient to target the PRP for degradation by Lon in vivo.
-In contrast, the UmuD-PRP fusion is unstable in the lon+ background and displays a half-life of ~9 min.

-By constructing chimeric UmuD proteins, we determined that the amino-terminal tail of the UmuD proteins proximal to the Cys24-Gly25 cleavage site is mainly responsible for the difference in UmuDStand UmuDEc cleavage rates.
-suggesting that most of the enhanced cleavage properties can be attributed to the N-terminal tail (residues 1 to 29) of UmuDSt.
-This region contains the cleavage site and not the active catalytic site of the protein, which leads us to conclude that UmuDSt is, in fact, cleaved more efficiently because it is a better substrate than UmuDEc.
