Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Essential component of the PAM complex, a complex required for the translocation of transit peptide-containing proteins from the inner membrane into the mitochondrial matrix in an ATP-dependent manner. Constitutes the ATP-driven core of the motor and binds the precursor preprotein. Required for the import of the processed frataxin homolog YFH1 into the mitochondrion (By similarity).By similarity
Acts as a non-catalytic component of endonuclease SceI (endo.SceI), which cleaves specifically at multiple sites on mitochondrial DNA and produces double-stranded breaks. SSC1 confers broader sequence specificity, greater stability, and higher activity on the catalytic subunit.3 Publications

Caution

S.cerevisiae displays strain polymorphism with regard to Endo.SceI endouclease activity. This is due to the mitochondrion-encoded, catalytic subunit ENS2, which exhibits strain polymorphism. It can be either present as continuous ORF in the mitochondrial genome (e.g. strain IAM 4274), present but disrupted by the insertion of GC clusters (e.g. strain D273-10B/A), or completely absent in the mitochondrial genome (e.g. strain S288c).Curated

<p>The checksum is a form of redundancy check that is calculated from the sequence.
