General description

Leucine Aminopeptidase belongs to the family of metalloprotease.

Application

Leucine Aminopeptidase, microsomal from porcine kidney has been used in the isolation of neprilysin (NEP) from rodent brain-C5 and for peptide digestion.

Biochem/physiol Actions

Leucine Aminopeptidase possesses broad substrate-specificity. It hydrolyzes peptides up to the proline residue and does not continue to degrade beyond proline.

Physical form

Suspension in 3.5 M (NH4)2SO4 solution, pH 7.7, containing 10 mM MgCl2

Other Notes

One unit will hydrolyze 1.0 μmole of L-leucine-p-nitroanilide to L-leucine and p-nitroaniline per min at pH 7.2 at 37 °C. (At 25 °C, approx. 40% of the activity at 37 °C is obtained.) The activity obtained using L-leucine p-nitroanilide as substrate is 2-5 times that obtained with L-leucinamide as substrate.
