DESCRIPTION: RecName: Full=Cytosol aminopeptidase; EC=; AltName: Full=Leucine aminopeptidase 3; Short=LAP-3; AltName: Full=Leucyl aminopeptidase; AltName: Full=Peptidase S; AltName: Full=Proline aminopeptidase; EC=; AltName: Full=Prolyl aminopeptidase;
FUNCTION: Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides.
CATALYTIC ACTIVITY: Release of an N-terminal amino acid, Xaa-|- Yaa-, in which Xaa is preferably Leu, but may be other amino acids including Pro although not Arg or Lys, and Yaa may be Pro. Amino acid amides and methyl esters are also readily hydrolyzed, but rates on arylamides are exceedingly low.
CATALYTIC ACTIVITY: Release of N-terminal proline from a peptide.
COFACTOR: Binds 2 zinc ions per subunit. One zinc ion is tightly bound and essential for enzyme activity, while the second metal coordination site can be occupied by zinc, magnesium or manganese to give enzymes of different activities (By similarity).
SUBUNIT: Homohexamer.
SIMILARITY: Belongs to the peptidase M17 family.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on P28838
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
