Revision19-June-2008 RFH
DescriptionNative endopeptidase Lys-C from Achromobacter lyticus. Lysyl endopeptidase is a serine protease secreted by soil bacteria and specifically hydrolyzes amide and peptide ester bonds at the carboxylic side of lysine and S-aminoethylcysteine residues. Optimal pH: 9.0-9.5.
FormLyophilized
Recommended reaction conditionsAmidase Activity: Materials Required: •Reagent A: 200 mM AMP, pH 9.5 (dissolve 4.2 g 2-amino-2-methyl-1,3-propanediol in 150 ml H2O; adjust the pH to 9.5 with 1 M HCl; add H2O to a final volume of 200 ml) •Reagent B: 2.5 mM Bz-Lys-pNA (dissolve 22.6 mg Nα-benzoyl-DL-lysine-p-nitroanilide in 900 ml H2O) •Reagent C: enzyme diluent (dissolve 240 µg 2-amino-2-hydroxymethyl-1,3-propanediol in 900 ml H2O; adjust the pH to 8.0 with 0.1 M HCl; add H2O to a final volume of 1 L •Reagent D: enzyme solution (dissolve 1 vial enzyme in 1 ml H2O; dilute 100 µl to a final volume of 25 ml with Reagent C) •45% Acetic Acid (stop solution) Protocol 1. Add 2.6 ml Reagent A to 300 µl Reagent B and pre-incubate at 30°C to equilibrate the temperature. 2. Add 100 µl Reagent D and incubate for 25 min at 30°C. Include 100 µl Reagent C alone as a control. 3. Add 1 ml 45% acetic acid to stop the reaction. 4. Measure the absorbance at 405 nm. 5. Calculate the activity: Amidase Activity (AU/vial) = [(Atest-Acontrol)/25] x [1/9.62] x [4/0.1] x 250
