IntEnz Enzyme Nomenclature


Accepted name:
endopeptidase Clp
Other names:
ATP-dependent Clp protease
Clp protease
caseinolytic protease
endopeptidase Ti
protease Ti
Systematic name:



An enzyme from bacteria that contains subunits of two types, ClpP, with peptidase activity, and ClpA, with ATPase activity. The ClpAP complex, which displays ATP-dependent endopeptidase activity, has the composition (ClpP14ClpA6)2 [4]. ClpP is the type example of peptidase family S14.
