Protein

Cytosol aminopeptidase

Gene

LAP3

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides.

Catalytic activityi

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.
Release of N-terminal proline from a peptide.

Cofactori

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).By similarity
