Description

General description

Recombinant tag-free Achromobacter lyticus Lys-c (lysyl-endopeptidase) (206-473aa) was expressed in E.coli cells.

Overview
Lysyl-endopeptidase (Lys-c) was isolated from the Gram-negative soil bacterium Achromobacter lyticus by Msaki et al. The protein hydrolyzes amide and peptide ester bonds at the carboxylic side of lysine and S-aminoethylcysteine residues making it an important tool for enzymatic protein sequencing and Lys-X compound synthesis.

Specificity

This enzyme hydrolyzes amide and peptide ester bonds at the carboxylic side of lysine and S-aminoethylcysteine residues, at a catalytic pH range of 9.0-9.5, catalytic temperature range of 30-37 °C.

Application

The enzyme functions optimally between 30-37 °C and suffers from degradation when subjected to temperatures above 50 °C. Lysyl-endopeptidase retains complete activity after incubation in 4M urea or in 0.1% SDS solution for up to 6 hours at 30 °C.

Packaging

1mg/ml in Plastic

Preparation Note

Catalytic pH range 9.0-9.5. Catalytic temperature range 30-37 °C.

Storage and Stability

Store product at -20°C for up to one year. Avoid freeze/thaw cycles.
