| Enzyme Function | FUNCTION: Catalytic component of the mitochondrial inner membrane peptidase (IMP) complex. IMP catalyzes the removal of signal peptides required for the targeting of proteins from the mitochondrial matrix, across the inner membrane, into the inter-membrane space. The two catalytic IMP subunits seem to have non-overlapping substrate specificities. IMP2 substrates include nuclear encoded CYB2, mitochondrially encoded COX2 and cytochrome c1. Required for the stability of IMP1. {ECO:0000269|PubMed:15118906}. |
