Background:
LAP3(Leucine aminopeptidase 3) is also named as LAPEP PEPS(peptidase S) and belongs to the peptidase M17 family.It can catalyzes the removal of unsubstituted N-terminal amino-acids from various peptides and be presumably involved in the processing end regular turnover of intracellular proteins.PEPS is found in a wide variety of tissues and cultured cells but not in red cells and skin.The enzyme can utilize several di- tri- and tetrapeptides as substrates and is the slowest migrating of the peptidases after electrophoresis.(PMID:689684).
