GENERAL STABILITY
ORGANISM
UNIPROT
LITERATURE
stable protein even at high concentrations of chaotropic agents
the addition of glycerol further increases the thermostability of the enzyme
the enzyme shows higher activity in sodium citrate buffer than sodium phosphate buffer at pH 6.0 and higher activity in sodium phosphate buffer than glycine buffer at pH 8.0
-
truncation of the C-terminal extension results in greater stability and solubility than the wild type, as well as a lower sensitivity to the presence of added metal ions
unstable in diluted solutions
-
urea, 2 M irreversible denaturation
