Protein

Presequence protease 2, chloroplastic/mitochondrial

Gene

PREP2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

ATP-independent protease that degrades both mitochondrial and chloroplastic transit peptides after their cleavage. Also degrades other unstructured peptides. Specific for peptides in the range of 10 to 65 residues. Shows a preference for cleavage after small polar residues and before basic residues, but without any positional preference.1 Publication

Cofactori

Binds 1 zinc ion per subunit.
Binds 2 Magnesium ions per subunit.By similarity

Enzyme regulationi

Completely inhibited by the metal chelator orthophenanthroline.
