The Clp protease has an active site catalytic triad. In E. coli Clp protease, ser-111, his-136 and asp-185 form the catalytic triad. Swiss:P48254 has lost all of these active site residues and is therefore inactive. Swiss:P42379 contains two large insertions, Swiss:P42380 contains one large insertion.
