一般描述
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.
特异性
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 ℃.
应用
The enzyme functions optimally between 30-37 ℃ and suffers from degradation when subjected to temperatures above 50 ℃. Lysyl-endopeptidase retains complete activity after incubation in 4M urea or in 0.1% SDS solution for up to 6 hours at 30 ℃.
包装
1mg/ml in Plastic
制备说明
Catalytic pH range 9.0-9.5. Catalytic temperature range 30-37 ℃.
重悬
Reconstitute in sterile water.
储存及稳定性
Store product at -20℃. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles once the protein has been resolubilized in sterile water.
其他说明
For R&D only.
