Mitochondrial processing peptidase complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Metalloprotease which cleaves off the N-terminal presequence from nuclear encoded mitochondrial precursor proteins, such as the sequence that targets the proteins to the mitochondrial matrix. Common features for cleavage of the extension peptides by MPP are a proximal basic amino acid residue, usually arginine at the P2 position, distal N-terminal basic residues generally 3-10 residues from the proximal arginine and an aromatic or less often another type of bulky hydrophobic residue at position P1'; MPP also prefers polar residues such as histidine, serine, and threonine at positions P2' and P3'.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
