GENERAL STABILITY
ORGANISM
UNIPROT
LITERATURE
62% of activity is retained at 2.0 M NaCl
beta-glucanase IV highly unstable
-
operational stability of the immobilized S296C variant is optimal with milled beads suggesting applicability of the immobilized enzyme on the smallest particles for continuous substrate conversion under industrially relevant conditions. S296C bound to the large beads shows a somewhat lower operational stability
The enzyme purified is found to be highly stable between 30 and 40°C for 1 h in citrate-phosphate buffer (pH 7.0)
-
very unstable during dilution and dialysis, addition of Ca2+ and bovine serum albumin partly restores activity
-
