Descrizione

General description

Leucine Aminopeptidase (LAP) from porcine is a 320-kDa exopeptidase present in cytosol. It contains zinc in its structure and belongs to the M1 and M17 peptidase families. LAP display bi-lobed structure and has the catalytic domain at the C-terminus and a variable N-terminal domain.

Application

Leucine Aminopeptidase, microsomal from porcine kidney has been used in aminopeptidase N (APN) inhibitor screening assay in adenocarcinoma cell line ES-2 and in the inhibition kinetic studies with APN inhibitor.[1]

Biochem/physiol Actions

Leucine Aminopeptidase (LAP) catalyzes protein hydrolysis at the leucine residue at N-terminal. An altered level of LAP is implicated in tumor proliferation and progression. LAP is a potential biomarker for ovarian epithelial cancer therapy. Porcine LAP hydrolyzes glycine and arginine substrates.

Physical form

Contains primarily phosphate buffer salts, pH 7.0

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.

  According to the Enzymatic Assay for Leucine Aminopeptidase, Microsomal Enzyme Solution, prepare a solution containing 0.10 - 0.15 unit/ml of Leucine Aminopeptidase, Microsomal in cold deionized water immediately before use.
  More information can be found at https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/356/218/l6007enz.pdf.
  This formulation contains phosphate buffer salts. For reconstitution, storage, and use of this product, 50 mM Sodium Phosphate Buffer, pH7.2, is a suitable solvent.

I recently purchased Leucine Aminopeptidase from porcine kidney Cat # L6007-25UN. I'd like to inquire how many mgs of protein is in one vial.

  The milligrams of protein per vial will depend on the units/mg protein defined on the product's certificate of analysis. For example, lot SLCM3898 reports specific activity of 19 units/mg protein. This results in approximately 1.3 mg of protein per vial for this particular lot. The protein content of this lot of material is reported at 61%, therefore the total mass of solid material in the 25UN vial will total around 2.2 mg.
