LAP3 (NM_015907) Human Recombinant Protein

Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides.[UniProtKB/Swiss-Prot Function]

LAP3 activity verified in a biochemical assay: Leucine aminopeptidase 3 (LAP3) activity was measured in a fluorescent biochemical assay. LAP3 catalyzes the removal of unsubstituted N-terminal amino acids from various peptides and is most active on leucine. LAP3 activity was measured in a 100 µl reaction mixture containing 1 mM L-leucine 7-amido-4-methyl coumarin (Leu-AMC), 50 mM Tris, pH 8.0, 4 mM MgCl2, and 1 mM MnCl2. Cleavage of leucine from the AMC moiety results in a strong increase in fluorescence intensity. Fluorescence was measured over time with an excitation wavelength of 380 nm and an emission wavelength of 460 nm. The activity of the enzyme in this system remained constant over six hours.

Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
