Descrição geral

Leucine Aminopeptidase (LAP) from porcine is a 320-kDa exopeptidase present in cytosol.[1] It contains zinc in its structure and belongs to the M1 and M17 peptidase families.[2] LAP display bi-lobed structure and has the catalytic domain at the C-terminus and a variable N-terminal domain.[3]

Aplicação

Leucine Aminopeptidase, microsomal from porcine kidney has been used in aminopeptidase N (APN) inhibitor screening assay in adenocarcinoma cell line ES-2[4] and in the inhibition kinetic studies with APN inhibitor.[5][6]

Ações bioquímicas/fisiológicas

Leucine Aminopeptidase (LAP) catalyzes protein hydrolysis at the leucine residue at N-terminal.[1] An altered level of LAP is implicated in tumor proliferation and progression. LAP is a potential biomarker for ovarian epithelial cancer therapy.[2] Porcine LAP hydrolyzes glycine and arginine substrates.[3]

Definição da unidade

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.

Questions

1–2 of 2 Questions  
  1. I would like to know the optimum solvent for dissolving, storing and using this reagent (Cat # L6007-25UN).

    1 answer
    1. 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.

      Helpful?

  2. 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.

    1 answer
    1. 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.
