catalytic Activity CATALYTIC ACTIVITY: Reaction=The enzyme cleaves the 36-Pro-Pro-37 bond of cysteine desulfurase (EC 2.8.1.7) removing three amino acid residues (Tyr-Ser-Pro) from the N-terminus after cleavage by mitochondrial processing peptidase.; EC=3.4.11.26; Evidence={ECO:0000250|UniProtKB:P40051};
DNA Binding
EC Number 3.4.11.26
Enzyme Function FUNCTION: Aminopeptidase which cleaves preprotein intermediates that carry destabilizing N-ter amino acid residues after the mitochondrial processing peptidase (MPP) cleavage site and is thus critical for stabilization of the mitochondrial proteome. {ECO:0000250|UniProtKB:P40051}.
